We focus on vaccine design, development and delivery. We are in trials in China and the Philippines to determine if administration of schistosome vaccines to water buffalo and cattle will help interrupt transmission of this disease. We also study the negative impact helminth infection has on vaccines in general. We are working with collaborators at the University of Pennsylvania and Advaxis Inc., to develop Listeria vector HIV-1 vaccines that drive the desired, vaccine-specific immune responses in helminth-infected recipients. We recently developed VacSIM, a “plug and play” new vaccine delivery platform. VacSIM enhances antigen presenting cell recruitment and activation to the vaccine delivery site via slow release of vaccine components. We are currently testing VacSIM with malaria and influenza vaccines.

My research explores the ecology and evolution of host-parasite interactions in natural populations. I am especially interested in the effects of host behavior on pathogen transmission, and in genetic and environmental determinants of host susceptibility and parasite virulence. Examples of questions I’ve focused on include: How does seasonal long-distance migration affect parasite transmission and host-parasite coevolution? Does social contact in animals increase their exposure to infectious disease? How does seasonality of breeding and social behavior affect disease spread? I am also interested in the intersection of infectious disease ecology and wildlife conservation

We are an interdisciplinary research group at the interface of carbohydrate research and immunology. Our objective is to explore the treatment of and protection from infectious diseases and cancer by understanding key molecular and cellular interactions between the components of the immune system and carbohydrate antigens associated with microbes or cancers.
Our research program is directed at: delineating immune mechanisms involved in the carbohydrate-mediated adaptive immune response, and designing, synthesizing and testing vaccine targets against model pathogens and cancers. Our research approach involves: (1) identification of the molecular interactions involved in uptake, processing and presentation of carbohydrate antigens by the antigen presenting cells (APCs), (2) isolation and characterization of T cells and their epitopes generated from model carbohydrate antigens, (3) understanding the basis for cellular and humoral immune responses induced by carbohydrate presentation and recognition that enable eradication of disease-causing agents, (4) design and synthesis of new-generation therapeutic and/ or prophylactic agents based on the knowledge gained from mechanisms discovered.

I take a broad quantitative perspective to address applied questions in infectious disease epidemiology. My research spans multiple pathogen systems (HIV, Ebola, anthrax, rabies) but is united by an overarching theme: the integration of mathematical and statistical models with empirical data to understand infectious disease processes and how to control them. I use simulation models of how diseases spread at the population level an to interpret available data and to plan rigorous empirical studies. My research particularly focuses on this intersection between epidemiological study design and transmission dynamics–that is, I aim to improve study design and interpretation by understanding the dynamical transmission processes underlying an epidemic and how they might bias studies.

I am a molecular virologist with experience in several virus systems, including retroviruses, filoviruses, paramyxoviruses, and recently arenaviruses, alphaviruses, and flaviviruses. Throughout my career I have focused on how viruses enter cells, both at the molecular level, examining small conformational changes that occur in viral fusion proteins, as well as the cellular level, determining the cell factors that facilitate virus entry. Currently, the lab is focused on two areas, arenavirus entry and arbovirus transmission and pathogenesis. We examine arenavirus entry using biochemical approaches to define microdomains within the Lassa fever virus glycoprotein complex, specifically the receptor binding sites, neutralizing epitopes, and the regions required for fusion activation. The arbovirus transmission studies are focusing on mosquito transmission under different environmental variables (temperature, humidity, etc). In addition, we have started work defining Zika cell tropism and Zika pathogenesis in the brain using a variety of models. The Zika work is a collaborative effort with several labs at UGA (Moore, Chen, Stice, and Murdock).

I have broad ecological research interests in marine community and population ecology that involve the study of the effects of parasites on communities and species interactions. My work on parasites is focused most intensively on ecological parasitology and is concentrated in three general areas: 1) Understanding what environmental factors control parasite abundance and diversity, 2) Examining the effects of parasites on hosts and community structure, and 3) Developing parasites as tools for conservation applications, particularly as biological indicator species. I have focused particular attention on the parasites associated with non-native species, including the novel parasites they vector into new regions and the parasite escape they experience by leaving many of their native parasites behind upon introduction. I work extensively with digenetic trematode parasites, particularly in mollusc and crustacean hosts.

The art of stealing blood requires that arthropods have the ability to circumvent the efficient mechanisms vertebrates have in place to maintain hemostasis, including platelet aggregation, vasoconstriction, and clotting. This is accomplished using a remarkable array of salivary proteins. We have taken a comparative approach to the study of these salivary components, working with saliva from mosquitoes, triatomine bugs, and ticks. Novel proteins and peptides identified to date include apyrases (ATP/ADP diphosphohydrolases), lipocalin-type proteins that inhibit platelet responses to collagen and ADP, tachykinin peptides which closely mimic endogenous vasodilators, and a family of nitrophorins that function as a storage and transport system for nitric oxide. Our focus also includes the immune response that develops in the host in response to salivary antigens. This response is also manipulated by components of the saliva, and we are currently characterizing these immunomodulators. We believe that the vector modifies the environment of the bite site in a variety of ways that tend to favor parasite or pathogen entry into the host, and we anticipate that identification of the salivary components involved and their mode of action will lead to novel strategies for blocking transmission

The Docampo lab discovered acidocalcisomes, acidic organelles rich in calcium and phosphorus that are conserved from bacteria to man For the last few years, the lab has focused on the functions of these organelles in a variety of cells, including trypanosomatids, malaria parasites, Chlamydomonas, Dictyostelium, bacteria, human platelets, and insect, chicken, and sea urchin eggs.
The Docampo lab also found that acidocalcisomes are rich in pyrophosphate and short- and long-chain polyphosphate and that polyphosphate has a variety of novel functions in eukaryotes, from an osmoregulatory function in trypanosomes to a potent procoagulant and antifibrinolytic action in human blood. The discovery of high levels of pyrophosphate in the acidocalcisomes led to the use of pyrophosphate analogs, currently used in the treatment of osteoporosis and other bone diseases (bisphosphonates), as potential chemotherapeutic agents against parasitic protists. Some of these bisphosphonates have been shown to produce radical cures in animal models of leishmaniasis

I am a basic-science investigator whose research interests lie in the broad area of microbial metabolism and cell function. Basic science generates new knowledge that often translates into practical applications. Research universities are unique settings where connections between basic and applied scientists are stimulated. In my professional field, this connectivity is greatly enhanced as a function of the breadth and depth of the areas of microbiology represented within a university like UGA.
My research group focuses on three areas of cell function:
Mechanisms of rapid response to stress. Unicellular organisms have evolved sophisticated mechanisms to deal with rapidly changing environments that can impose stressing conditions that jeopardize cell survival. Because stressors can be transient, response mechanisms must be rapid, effective and reversible.
Complex metabolic pathway analysis. For over two decades, we have investigated microbes make coenzyme B12, an essential human nutrient that is manufactured exclusively by microbes. Metabolic stress caused by toxic metabolites. Our work in this research area centers on the catabolism of fatty acids that are abundant in soil and the gut, two environmental niches of great interest to human health. Notably, the catabolism of these compounds generates potent cell inhibitors whose mode of action is unknown.

Research in my lab focuses on host-parasite interactions in wild animal populations. We investigate how behavioral, ecological, and physiological processes at the individual level shape interactions between hosts and their parasites. We also examine the consequences of these interactions for host fitness and large-scale patterns of disease. Our work combines field studies with laboratory approaches and theory to address core questions about the ecology and evolution of infectious diseases in nature. Ongoing topics of interest in my lab include ecological and immunological consequences of microparasite-macroparasite coinfection & bi-directional interactions between & host social and reproductive behavior and infectious disease; and links between biodiversity and disease risk.
Dr. Fu has found that attenuated rabies virus activates, but pathogenic rabies virus evades, the host innate immune responses including activation of IFN pathways, induction of inflammation and apoptosis. He has further found that evasion of the host immune responses of the pathogenic virus is due to a restriction of the G protein expression. These studies have led to the creation of infectious virus clones that express innate immune molecules. These viruses have the ability to induce innate and enhance the adaptive immune responses and thus can be developed as avirulent rabies virus vaccines as well as therapeutic agents.
Furthermore, Dr. Fu is involved in the research of neuropathogenesis of rabies as well as other virus infections such as a respiratory syncytial virus, human metapneumovirus, and influenza virus. Dr. Fu is part of the NIAID Center of Excellence for Influenza Research and Surveillance.
My research interest resides in the use of molecular biology approaches to control respiratory diseases of poultry. In particular, we are interested in the control of infectious laryngotracheitis virus, avian influenza, and avian mycoplasmas. The control of respiratory diseases in large populations of poultry represents an immense challenge because it is necessary to have sensitive and specific diagnostic tools, extremely effective biosecurity measures, and the use of effective vaccines. The use of molecular biology has been pivotal in the advances of molecular epidemiology, molecular diagnostics and the development of safer recombinant vaccines for poultry.

I explore mathematical and computational models that connect genes to ecology. My current direction of research includes (i) genetic control of invasive species via autocidal organisms, which are produced via phenotypic and genotypic manipulations, and (ii) landscape epidemiology of malaria, particularly in regards to the design of public health policies that address asymptomaticity and the spread of drug-resistant genes and in areas of low endemicity. I also specialize in data management of very large and heterogeneous biological datasets.

Dr. Haidekker’s area of expertise lies in the bioinstrumentation/biosensing and the bioimaging areas. His primary research focus are fluorescent environment-sensitive probes, specifically, viscosity-sensitive molecular rotors. There is a wide range of applications for real-time nanoscale viscometers. Many diseases are associated with blood and plasma viscosity changes. Present-day viscometers are cumbersome to use, relatively inaccurate, and preclude serial measurements due to high maintenance effort. Molecular rotors do not have these disadvantages. The microscale resolution is essential for microscopic techniques (viscosity of cell compartments), where mechanical viscometers cannot be used at all. Molecular rotors can be targeted to specific sites, such as pathogen proteins, where the report specific binding with a change of their fluorescent properties. Molecular rotors can also be attached to fiber-optic tips, which in turn can be injected and used as in vivo sensors. A recently-discovered sensitivity of molecular rotors towards fluid shear stress can be used to explore non-Newtonian fluid behavior and to build closed-loop flow control for microfluidic systems.

As a Veterinary Entomologist, my research has focused on suppression and control of ectoparasitic and vector arthropods such as mosquitoes, fleas, ticks, mites, biting flies, higher flies, and beetles. Generally, we take a big-picture approach, working on the ecology of arthropods affecting human and animal health, and applying ecological interventions to manage pest populations and interrupt disease transmission.
Systems in which we have conducted research include companion animals and flea control; whitetail deer and biting midges transmitting bluetongue and epizootic hemorrhagic disease viruses; cattle and biting flies; biological control of mosquitoes; fly suppression around dairies; and ecology and suppression of ectoparasites and arthropod pests in poultry (layer, broiler, and breeder) production operations. All of these pertain to the “One Health” concept, with human and animal health being affected by these arthropods and the pathogens they transmit. We are particularly invested in suppressing the vectors as an intervention to interrupt disease transmission and protect the health of humans and their food and companion animals.

The primary research focus of my laboratory is to measure, understand and solve the problems presented by drug-resistant parasites. Parasite drug resistance is now recognized globally as one of the greatest health threats to grazing livestock. Also, in recent years there has been a dramatic increase in the use of mass drug administration to reduce the morbidity associated with helminth infections of humans, raising the likelihood that anthelmintic resistance may become a public health concern in the near future. To address this problem, my laboratory pursues research projects with four different areas of emphasis: 1. Measuring the prevalence of drug resistance 2. Studying the molecular basis of anthelmintic resistance 3. Developing in vitro and molecular diagnostic assays to detect emerging resistance in nematode populations 4. Studying and developing novel and sustainable approaches to parasite control that rely less heavily on chemical anthelmintics

The research of our laboratory is focused on understanding how infection at mucosal surfaces regulates the mechanisms used by CD8 T cells to migrate, differentiate, and survive long-term as memory cells in the mucosa under both homeostatic and inflammatory conditions. Using predominately mouse models of influenza infection, we are studying 1) how respiratory infection differentially regulates expression of cytokines, chemokines, and specific metabolites in the respiratory milieu, 2) how CD8 T cells responding to the respiratory infection interpret these environmental signals and 3) how cells of the innate immune system, particularly NK cells, are regulated in the lung and respond to these identical environmental signals, which together can either directly or indirectly shape the subsequent anti-influenza T cell response by affecting their lineage commitment and requirements for longevity. It is our hope that understanding these processes will provide information to intelligently design a better CD8 T cell-based influenza vaccine that does not require the currently mandated yearly reformulation.

Dr. Lafontaine’s research program consists of identifying and characterizing surface antigens that are expressed by the gram-negative bacteria Moraxella catarrhalis, Burkholderia pseudomallei, and Burkholderia mallei, with emphasis on molecules functioning as adherence factors. Our lab’s hypothesis is that these molecules are potential vaccine antigens. Furthermore, adherence is an important step in pathogenesis by most infectious agents and we believe that studying this process will shed some light on the means by which the organisms cause disease. M. catarrhalis is a major causative agent of otitis media, sinusitis, as well as respiratory infections in patients with the chronic obstructive pulmonary disease. Very little is known about pathogenesis by M. catarrhalis and there is currently no vaccine for this bacterium. B. pseudomallei causes melioidosis whereas B. mallei cause glanders. These two closely related bacteria are potential bioterrorism agents and there is an urgent need to understand their biology as well as develop vaccines.

The Locklin Group is interested in growing functional polymers from surfaces (“grafting from”) using different Surface-Initiated Polymerization techniques. This is a technique based on the growth of polymer molecules at the surface of a substrate (such as glass, metal, or plastic) in situ from a surface-bound initiator, which results in the covalent attachment of polymer molecules to this substrate. Polymer layers in which the polymer chains are irreversibly immobilized to the substrate are especially attractive for a wide variety of applications, as these layers have excellent long-term stability, even in rather adverse environments. In addition to improved stability, the number of functional groups present at a surface can be greatly enhanced by connecting large polymer molecules with functional groups (present in each monomer repeat unit) to the surface. Currently, we are using ring-opening metathesis polymerization (ROMP), Kumada transfer polycondensation (KCTP), atom-transfer radical polymerization (ATRP) and conventional free radical polymerization to grow functional coatings for the following applications: Stimuli-responsive surfaces, photo-induced mechanical motion, sensors for biological arrays, antimicrobial coatings, and enzymatic biofuel cells.

Vesicular stomatitis virus, dengue viruses, West Nile virus, bluetongue viruses, and epizootic hemorrhagic disease viruses are just a few of the viruses we work with.
Over the past several years most of my research efforts have been devoted to the development of semi-analytical models and remote sensing techniques for monitoring coastal and shallow marine ecosystems. One of my research interests is in the area of cyanobacterial harmful algal bloom (CyanoHABs). CyanoHABs have been broadly recognized as a human and animal health problem because of the wide varieties of toxins associated with them. Despite the environmental health, human health, and animal health risks, there is no established rapid monitoring program to periodically evaluate the spatial distribution of cyanobacteria. My research interest is in developing a remote detection tool for rapid detection of cyanoHABs and quantification of the cyanobacteria concentration in freshwater systems. My ultimate goal is to develop an automated early detection and warning tool using remote sensing that will be used to warn public health officials of impending risks and to assess exposures for CyanoHAB-related outbreaks. These data could improve response times for implementing measures to reduce the frequency and severity of these blooms in future.

Research in my laboratory centers on the characterization of calcium homeostasis pathways in Toxoplasma gondii and trypanosomes. We discovered a new organelle, which we named the acidocalcisome because of its acidity and a large content of calcium. While characterizing the composition and function of this organelle we found that it contains large amounts of phosphorus in the form of polyphosphate and they were similar to the previously described “polyphosphate bodies”. Acidocalcisomes have now been shown to be lysosome-related organelles and found in bacteria as well as in mammalian cells.
One of the acidocalcisome markers, the vacuolar-H+-pyrophosphatase also localizes to a novel compartment in T. gondii with similar composition and function to the plant vacuole, which we named plant-like vacuole (PLV). This organelle contains a vacuolar-H+-pyrophosphatase, 2 aquaporins or water channels, a vacuolar-H+-ATPase, other transporters, and hydrolases. Experimental evidence indicates that this organelle is linked to the endosomal pathway of the parasite and may be also involved in storing important enzymes used for the maturation of secretory proteins. We are presently studying the functions and biogenesis of this organelle.
We are also interested in the isoprenoid pathway of Toxoplasma gondii. Work in collaboration with other laboratories is centered on testing isoprenoid pathway inhibitors against Toxoplasma growth in vitro and in vivo.

Influenza viruses are pathogens of great significance to public and animal health. Dr. Perez studies the changes that allow influenza viruses to jump animal species and cause disease in humans. Dr. Perez’s long-term goal is to provide a comprehensive map of molecular changes associated with animal-to-human (A2H) and human-to-human (H2H) transmission of influenza viruses. Such information is crucial to better prepare against influenza viruses with zoonotic potential and/or of pandemic concern. Dr. Perez’s laboratory uses a wide range of in vitro and in vivo approaches to better understand influenza virus host range and improve existing and/or develop new universal vaccines and antivirals. Dr. Perez contributions on the role of quail as a host for influenza viruses with expanded host range was one argument that led to banning live quail in Hong Kong poultry markets in 2002. Later, Dr. Perez’s group demonstrated the molecular aspects responsible for respiratory droplet transmission of avian influenza viruses of the H9 and H7 subtypes in ferrets (mammals). During 2005-2011, Dr. Perez was responsible for the program “Prevention and Control of Avian Influenza in the US”, a USDA-funded multi-institutional project with a comprehensive research and surveillance structure. Since 2007, The Perez’s lab is part of the NIAID-funded CEIRS Center for Research on Influenza Pathogenesis (CRIP), led by Dr. Adolfo Garcia-Sastre at Icahn School of Medicine at Mount Sinai, New York. In April 2015, Dr. Perez joined the Department of Population Health, University of Georgia as Georgia Research Alliance Distinguished Investigator and Caswell S Eidson Chair in Poultry Medicine within the Poultry Research and Diagnostic Center. Since 2017, Dr. Perez is also affiliated with the Center for Vaccines and Immunology.

I am currently a tenured Associate Professor in the Department of Infectious Diseases and a full member of the Center for Tropical and Emerging Global Diseases, one of the largest parasitology research groups in the country. I have extensive expertise in malaria research dating from my postdoctoral work at NIH, where I first worked on parasite resistance to antimalarial drugs, and later on the var gene family. My primary research interests are in host/malarial parasite interactions as mediated by adhesion proteins of the DBL superfamily, with our current focus being on the role of var2csa in placental malaria. Currently my laboratory is characterizing var2csa both at the functional level via protein studies, and by examining the genetic complexity of placental infections via both standard cloning techniques and via deep sequencing strategies. Recently we have also begun to characterize the antimalarial activity of a set of novel compounds related to AKT inhibitor-IV.

It is estimated that one-third of the world’s population is infected with Mycobacterium tuberculosis, with about 2 million deaths per year and a majority of these deaths occurring in the developing world. Effective treatment regimens are generally available, but accurate and inexpensive diagnostics and vaccines are not. My research program over the past decade at the Centers for Disease Control and Prevention and now at the University of Georgia has focused on identifying and studying mechanisms of M. tuberculosis pathogenesis, and using these factors as therapeutic, diagnostic and vaccine targets. Using the latest molecular tools, imaging technologies, and in vitro, ex vivo and in vivo models, we have identified several new virulence determinants and are in the process of testing the protective efficacy of novel vaccines and diagnostic tests based on these pathogenic factors.

Research in my laboratory investigates reactive oxygen species-based host-microbe interactions at the respiratory mucosa. We study mechanisms of reactive oxygen species production in airway epithelial cells and white blood cells and their importance in microbial killing, epithelial wound healing, recruitment of white blood cells and unfolding of the innate immune response. When out of control, reactive oxygen species can cause serious tissue damage and contribute to disease pathology in chronic inflammatory conditions of the airways such as cystic fibrosis and chronic obstructive pulmonary disease. In parallel, research interest in our group also focuses on roles of redox-active microbial toxins in virulence of Pseudomonas aeruginosa, the bacterium infecting the airways of majority of cystic fibrosis patients.

Although I am currently a biostatistician, through the mid-1980s I had a career as a field ecologist. Despite pursuing a career in biostatistics, I have maintained my interests in ecology through collaboration with ecologists at the University of Georgia and Pennsylvania State University. My training in spatial statistics is well suited to the investigation of the ecology and epidemiology of infectious diseases, the latter of which cannot be fully comprehended without the former. Bayesian hierarchical spatio-temporal models are well suited to describing the ecology of infectious diseases. Such models may include a process model, a data model, and a
prior model. The process model may be used to describe the data we would ideally like to but is impractical to obtain. For example, Markovian spatio-temporal models may be constructed based on difference equations to describe the transmission of an infectious disease in a spatially distributed population. The data model describes the distribution of the observable data conditional on the realization of the process model, while the prior model describes prior beliefs regarding all model parameters. Bayesian hierarchical modeling provides a framework for combining data from multiple sources as for example brought by the various investigators on a multi-disciplinary research team.

Over the past decade my students, postdocs and I have worked on a variety of research questions pertaining to parasites and diseases of wildlife species. Research foci have included conceptual studies on the genetic structuring of parasite populations, relationships between host social structure and transmission dynamics of parasites and diseases, studies of the ecology of prominent wildlife hosts for diseases like rabies, leptospirosis, canine distemper and parasites such as ticks and roundworms, and studies focused on optimization of mitigation and treatment programs for parasites and diseases of concern to human health. In addition, I served as the Assistant Director of the National Wildlife Research Center in Fort Collins Colorado for ~1.5 years, where I oversaw all of the center’s wildlife disease programs, namely those involving rabies, chronic wasting disease, avian influenza, and a variety of other pathogens of interest to human and domestic animal health.

We study African trypanosomes, unicellular eukaryotic protozoa that infect the bloodstream of mammals to cause sleeping sickness in equatorial Africa. While they reside in the mammalian bloodstream, trypanosomes are able to evade the host’s immune response by regularly changing their variant surface glycoprotein (VSG) coat, a process called antigenic variation, allowing long-term survival of these parasitic organisms within the host. Switching the VSG that is expressed is accomplished primarily by recombination of a new VSG gene into a telomeric expression site. Research in the laboratory has implicated a novel modified DNA base, called base J, in the regulation of VSG gene expression. This modified base represents a specific modification of thymine residues where a large glucose moiety is covalently attached to the base and extends into the major groove of the DNA helix. Therefore, understanding the mechanism/regulation of base J synthesis will help us understand the regulation of antigenic variation.
Unusually for a eukaryote, all trypanosome gene transcription is polycistronic where regulated gene expression is thought to rely solely on posttranscriptional processes rather than transcription initiation. However, we recently localized base J to the transcription start sites of polycistronic gene clusters where its removal led to changes in Pol II transcription initiation, gene expression, and virulence. The goal is to elucidate the mechanism of J regulation of gene expression and determine what role base J synthesis plays during essential changes that occur throughout the parasite lifecycle. Hopefully, these studies will lead ultimately to novel targets for anti-parasitic interference.

My laboratory studies pathogens of macrophages and the mechanisms used by these organisms to subvert innate immunity. The main focus of my lab is on the study of Mycobacterium tuberculosis and how this pathogen manipulates its host cell, the macrophage. Our past work shows that an important virulence factor of M. tuberculosis, a cell wall glycolipid called trehalose dimycolate, binds to the macrophage scavenger receptor, MARCO, and may use this interaction to dampen macrophage responses and impair mycobactericidal activity. We are also developing a mouse model to study the effects of intestinal helminth infection on various mycobacterial infections, such as with M. bovis and M. avium subspecies Paratuberculosis. Our laboratory also studies a protozoal parasite of feline monocytes and erythrocytes called Cytauxzoon felis. This parasite causes a severe, fatal infection in cats in this region. Our laboratory studies the immunopathogenesis of this disease, particularly the severe, systemic, inflammatory response that develops, in addition to developing culture conditions for the parasite.

Understanding the impacts of diseases on wildlife populations and the potential for wildlife species to act as reservoirs or sentinels for livestock, poultry, and human diseases represent the central missions of our lab. Most of our current work is oriented towards the epidemiology of viral and vector-borne diseases specifically bluetongue and the epizootic hemorrhagic disease viruses in white-tailed deer and avian influenza viruses in free-living duck and shorebird populations.
My current research interests are in transmissible spongiform encephalopathies (TSEs; prion diseases) using sheep cell culture as a natural model system to study prions. The overall objective is to investigate the cellular pathogenesis of prion diseases. Current areas of investigation include identifying determinants of permissiveness and identifying inhibitors of prions. Other collaborative work includes investigating the interaction of viruses and monocyte-derived cells, using organ culture to study virus-host interactions, and providing histopathology for a variety of other research projects.

My primary research interests are in the study of the interactions between insects, parasites, and beneficial symbionts. Projects include the characterization of 1) viruses and other microbes associated with insects, 2) insect immune defense responses, and 3) the interplay between the insect immune system and reproduction. Our laboratory is strongly interdisciplinary with projects that focus on genomics, the molecular and biochemical regulation of particular physiological processes, and the consequences of specific immune-microbial interactions on insect life history and evolution. Our work also involves a variety of different insects including mosquitoes, parasitoid wasps, and Lepidoptera (moths and butterflies).

As a biological anthropologist, I am interested in how people maintain health when they are frequently exposed to infectious disease. To date, my research has focused on lowland Bolivia where neglected diseases, such as soil-transmitted helminths, are a significant problem. My work and the work of my students examine the multiple pathways through which sociocultural and environmental change may affect health. We consider how educational and economic variation influence the distribution of infectious disease along with the value of local ethnomedical knowledge in treating disease. My research also examines the consequences of frequent exposure to infectious disease to child growth and nutrition. Overall, understudied diseases are an unfortunate daily reality of many populations and have important implications for the biological and social production of health.

My lab studies T. cruzi infection and Chagas disease. Although immunology is the key discipline in our group, we take a very broad view and incorporate peripheral areas of investigation as needed. Immunologically, we are particularly interested in T cell responses to T. cruzi – especially CD8+ T cells that can recognize parasite-infected host cells. We have delved deeply into various ‘omics – genomics, proteomics and transcriptomics – in order to know what it is that T. cruzi is presenting to the immune system at critical points in its development. We are active in the assembly, annotation and continued an exploration of the T. cruzi genome. The mechanism of evolution of the large gene families that are the major targets of immune responses – and how these contribute to immune evasion continues to occupy us. We have a growing interest in metabolomics as we believe that hsot-parasite metabolism may play a key role in parasite persistence. More recently, we have become significantly involved in drug discovery, in the use of existing drugs, and in the development of biomarkers for assessing treatment outcomes. We are highly cognizant of the need to apply our knowledge of the T. cruzi:host interaction to the real world effect that this parasite has on more than 15 million infected individuals. This ambition has taken us into translational research, such as the development of diagnostics and vaccines. Current vaccine efforts focus on the development of live attenuated parasite strains that can be used as transmission-blocking agents – when delivered to dogs and other reservoir hosts. We maintain a long-term collaboration and laboratory in Buenos Aires, Argentina where we study immune responses and treatment follow-up in a large cohort of human patients with chronic T. cruzi infection.

My research interests focus on understanding transmission and pathogenicity of zoonotic influenza virus infection and development of novel approaches to vaccination and the prevention and treatment of viral infections. This utilizes a variety of animal models and disease hosts including mice, ferrets, cats, and swine. Studies include understanding transmission and pathogenic potential of avian influenza virus field isolates, surveillance of non-contemporary mammalian influenza viruses, mutagenesis of influenza viruses, novel recombinant vaccine and vaccine delivery development, therapeutic applications of RNA interference, and understanding the role of microRNAs in infectious disease and neoplasia. Related to this I have contributed to genome-wide screening for host genes involved in viral (influenza, measles, RSV, polio) replication using siRNA libraries. I have also work on a variety of approaches for the development of human antibodies for the prevention and treatment of infectious diseases. More recently, my research has included the pathogenesis of respiratory syncytial virus (RSV) infection, development of RSV vaccines, and outcomes of respiratory virus co-infections. Finally, recent studies explore the innate immune response to viral infection is different host species, including human, swine, mouse, feline, alligator, and bat.

The research interest of our group is to develop translational disease intervention strategies for important human viruses and emerging infectious diseases of zoonotic origin. Our BSL2, BSL3, and BSL3Ag+ laboratories develop platform enabling technologies in pathogen biosensing using nanotechnology-based approaches, antiviral drugs using small molecule, RNAi-based drugs, therapeutic antibodies, and animal and human vaccines. In parallel, we investigate the mechanisms of immunity and disease pathogenesis associated with infection to better understand the conceptual and functional differences between innate and adaptive immune responses that provide the foundation necessary to facilitate vaccine and antiviral therapeutic protocols. The laboratories leverage the talents of academic, government and industry partners to promote “bench-to-bedside” vaccines and therapeutics.

The increasing prevalence of antibiotic resistance represents a major public health threat. The most common modes of resistance fall under several general categories: restricted uptake, increased efflux, drug inactivation, and target alteration. The particularly impermeable outer membrane of Pseudomonas aeruginosa provides a broad spectrum of intrinsic resistance, yet little research has been done on strategies to combat this specific mechanism of resistance. We are currently addressing the antibiotic permeability barrier present in P. aeruginosa through the development of nanomaterials capable of enhancing its sensitivity to a variety of antibiotics, thereby increasing the number of viable treatment options, and are also investigating the mechanism of action of the nanomaterials.

Basic issues of electronic transport on the nanoscale are fairly well understood in systems such as semiconductor quantum wires and point contacts, metallic point contacts, and even in molecular systems like single-walled carbon nanotubes. However, the same is far from true for organic molecular wires tethered between contacts. Molecular wires, especially biomolecules with nanometer size in nature, will be key components in nanoelectronics, as they offer much more than just charge transport and connection with the outside world. We are interested in an integrated approach that can be used to study all the parameters and thus obtain the most information SPM Bioimaging and Molecular Nanolithography: Define molecular nanopatterns for imaging and single molecular electronics study recognition of biological systems that permit observation of rarely populated transients that are difficult or impossible to capture using bulk measurements. In this research we are to detect biological events at the single-molecule level, which will be key to scientific advances in understanding, identifying, and developing therapies that promote human health.
