FACULTY

The Barton lab studies RNA viruses - viral RNA replication - and host-pathogen interactions involving viral RNA and endoribonucleases.

Specializes in understanding how T cells develop and help fight infection.

The Clark lab investigates bacterial-driven immune modulation in the respiratory tract. The upper respiratory tract is home to a diverse microbial community that includes both commensal and opportunistic bacterial pathogens. Research in the lab explores how exposure to these bacteria influences upper and lower respiratory tract inflammation and disease, with a focus on the innate immune response to acute infection.

The Colgan Lab studies mucosal inflammation with focus on intestinal inflammation in the context of inflammatory bowel disease and other GI diseases. Studies are aimed at understanding how epithelial and endothelial cells coordinate barrier function and inflammatory responses at mucosal surfaces. Our lab takes a multifaceted approach by investigating the relationships between gut microbiota, host immune system, genetic background, and environmental influences as it pertains to mucosal health and disease, with research emphasis on energy metabolism, host-microbe interactions, hypoxia-inducible factor, and innate immunity.

Our long-term goals are to develop novel approaches for treating immunorefractory cancers and to develop predictive models and diagnostics to identify compounds that sensitize tumors to T cell-based therapies.

The overall interest of the Doran Lab is the study of host - pathogen interactions in the central nervous system and the female reproductive tract. Our studies focus on major human pathogens including Streptococcus agalactiae (also known as Group B Streptococcus, GBS), a leading cause of invasive disease in newborns and certain adult populations including pregnant women. We seek to elucidate the mechanisms by which GBS colonizes the vaginal tract during pregnancy and penetrates the blood-brain barrier in the newborn to cause meningitis, as well as characterize host response to infection and colonization.

The Duerkop lab studies bacterial viruses (bacteriophages or phages) and their interactions with their hosts. The long-term goal of the Duerkop lab is to understand how phages and other forms of mobile DNA contribute to host-microbe interactions in the intestine and their overall impact on human health.

His primary areas of study are Immunology, Acquired immunodeficiency syndrome, Internal medicine, Vaccination and Viral disease. His Immunology research is mostly focused on the topic Immune system. His work carried out in the field of Immune system brings together such families of science as Antibody and Antigen.

The major focus of my research program is to elucidate pathways of innate immunity that can distinguish harmless microbes from pathogens, thereby enabling the host to mount responses that are commensurate with the threat.

Dr. Kuhn’s research program focuses upon understanding mechanistic connections between the gut mucosa and joints in the development of spondyloarthritis and rheumatoid arthritis.

The research in our laboratory focuses on new generation HIV-1 inhibitors and virus-host interactions. We employ complementary biochemistry, structural biology, pharmacology, molecular biology and virology approaches.

We study mechanisms of immune subversion and immune regulation during bacterial infections and other disease settings. We dissect strategies that microbes have evolved to thwart or manipulate immune responses and work to define host immune regulatory circuits that are manipulated by pathogens. Our studies focus on innate immune responses during mucosal and systemic infections. We are actively pursuing translation of information from our studies towards improved therapies for infectious, inflammatory, cancerous, and other diseases.

We combine bioinformatics and experimental work to understand the driving factors of human microbiota composition, host:microbe interactions, and the intersection with diet in a variety of disease contexts. Our work has a particular focus on HIV-positive and high HIV-risk populations, cancer and Clostridioides difficile infection.​

Emerging infections are a global public health threat. In the 21st century alone, we already have experienced devastating outbreaks of infectious disease, including diseases caused by mosquito-borne (e.g., chikungunya and Zika viruses) and respiratory RNA viruses (e.g., SARS-CoV-2). Our laboratory seeks to improve our knowledge of the molecular pathogenesis of these infections (i.e., what are the critical host-pathogen interactions that contribute to protection or pathology?) by addressing questions at the interface of immunology and virology/parasitology.

The mission of Dr. Maria Nagel’s lab is to dissect mechanisms by which viruses evade immune clearance and produce aberrant, chronic inflammation that leads to disease corresponding to affected sites. Research is predominantly focused on the pathogenesis of varicella zoster virus (VZV) and herpes simplex virus (HSV), as well as new exploratory studies on SARS-CoV-2. By understanding virus-host interactions, we can identify biomarkers that would assist clinicians in disease diagnosis and prognosis, as well as identify pathways that can be targeted to treat infection and associated inflammation.

Fungi are normal members of the human gut microbiome that are benign commensals in people. However, fungi can become pathogenic when the microbiome or immune system is perturbed. Candida species dominating the gut fungal community are notorious opportunistic pathogens capable of causing life-threatening disseminated infections. Candida species can also drive pathogenic inflammation in the gut and are associated with worsened inflammatory bowel disease in people. It is still largely a mystery as to how these fungi reside peacefully in the gut of most people. The goal of the Ost lab is to uncover the immune forces that constrain these fungi to a commensal state to prevent disease.

Delineating the effects of HIV infection on T cell function.

Our lab studies host-pathogen interactions with the goal of defining host and bacterial pathways involved in bacterial persistence. Bacterial interactions with the host involve dynamic exchanges where heterogeneity from both sides can lead to many different outcomes. Persistence occurs when the pathogen evades the host immune response and the host is unable to clear the invading pathogen, resulting in stable bacterial colonization. Individuals with persistent infections often do not respond to long-term or repeated appropriate antibiotic treatment and, importantly, serve as reservoirs for the development of antibiotic resistance.

We aim to study the chemical ecology of environmental and host-derived microbiome communities by developing broadly accessible experimental approaches. We accomplish this goal by combining modern and classical tools and techniques from a variety of scientific fields, including chemistry, microbiology, cell biology, molecular biology, and biochemistry.

His research group investigates the roles that cellular proteins play in viral replication cycles, and innate immune system factors that mediate frontline antiviral defenses and prevent cross-species virus transmission. They are interested in cellular systems that sense and respond defensively to viral RNA and DNA and also prevent autoimmunity to self nucleic acids.

We develop general-purpose computational approaches that integrate large-scale heterogeneous public datasets that lead to the mechanistic understanding of microbial genotypes, phenotypes, and diseases.

Our laboratory studies the interplay between the innate and adaptive immune response against retroviruses to conceptually advance vaccine and cure strategies against HIV/AIDS. We are specifically interested in “restriction factors” – host proteins that could directly inhibit retroviruses but we discovered also play critical roles in shaping adaptive immune responses. These factors could be regulated by Type I interferons, thus highlighting possibilities for clinical translation.

Mycobacterium tuberculosis survival during latent disease.

The biological functions of a cell are heavily influenced by its surrounding environment. This influence is achieved mostly through membrane proteins that mediate various informational exchange between the two bodies. Thus, it is vitally important to understand how these membrane proteins function, which is the overarching goal of our research. The main tools we use in the laboratory are cryo electron microscopy and X-ray crystallography.
