Theresa Alenghat, VMD, PhD Member, Division of Immunobiology

Theresa Alenghat, VMD, PhD, investigates central epigenomic pathways that regulate epithelial and immune cell homeostasis in the context of intestinal health and disease. The goal of her research is to provide insight into mechanisms underlying the host-commensal relationship and how this level of regulation affects the development of chronic diseases such as inflammatory bowel disease.

Claire A. Chougnet, PhD

Claire A. Chougnet, PhD, aims to understand T cell function and dysfunction at a molecular level in human disease, with a focus on defining the molecular mechanisms that underlie T cell dysfunction in HIV/AIDS, defining the molecular mechanisms responsible for immune dysfunction in aging, and understanding the development of T cell responses in very early life.

Senad Divanovic, PhD Member, Division of Immunobiology

Senad Divanovic, PhD, investigates the molecular mechanisms underlying the regulation of innate immune signaling and inflammation in: (a) development and progression of obesity; (b) development and progression of non-alcoholic fatty liver disease; and (b) induction of preterm birth. These studies, range from reductive analysis of TLR ligand signaling and challenge to the role of IL-17 axis to diverse experimental models of obesity and infection.

Fred D. Finkelman, MD

Fred D. Finkelman, MD, uses mouse models to study the roles of antibodies and cytokines in health and disease. Particular interests include allergic disorders, parasitic worm infections, and antibody-mediated disorders.

H. Leighton (Lee) Grimes, PhD Director, Cancer Pathology Program, Division of Experimental Hematology & Division of Pathology

H. Leighton (Lee) Grimes, PhD, focuses on the transcriptional control of normal and malignant hematopoiesis. The goal of his research is to understand how normal blood cells are formed, and to use this information to dissect the molecular pathogenesis of marrow failure and leukemia.

Andrew B. Herr, PhD Director of Admissions, Immunology Graduate Program

Andrew B. Herr, PhD, studies protein-protein interactions involved in immune receptor signaling and bacterial pathogenesis. His lab uses X-ray crystallography to solve the atomic structures of proteins along with techniques of biophysical chemistry to understand their interactions in solution. The goal is to understand the molecular basis for autoimmune responses and recurrent bacterial infections, and to develop new therapeutic applications.

John Hogenesch, PhD

Dr. Hogenesch's lab studies the mammalian circadian clock using genomic and computational tools. They use these tools to discover new clock genes, learn how the clock keeps time, and how it coordinates rhythms in physiology and behavior. This clock research drives development of genomic and computational methods that they apply to other areas of biology. Finally, they recognize biological complexity and conduct this research at the network, rather than single gene, level.

Michael B. Jordan, MD Member, Division of Bone Marrow Transplantation and Immune Deficiency

Michael B. Jordan, MD, specializes in caring for children with histiocytic disorders, primary immune deficiencies, or who are undergoing bone marrow transplantation. His laboratory focuses on understanding effector T cell function, immune regulation, and the pathogenesis of hemophagocytic lymphohistiocytosis. He is also conducting preclinical scientific studies in addition to a translational clinical trial.

Jonathan D. Katz, PhD

Jonathan D. Katz, PhD, is working to understand the role that autoreactive T lymphocytes play in the Immunopathogenesis of type 1 diabetes, the most common pediatric autoimmune disease. Major focuses include defining: (a) the control of autoreactive T cells via central and peripheral tolerance; (b) the role NKT cells play in regulating autoreactive T cells; and (c) the role dendritic cells play in activating and regulating autoreactive T cells in type 1 diabetes.

Ian P. Lewkowich, PhD

Ian P. Lewkowich, PhD, investigates the factors that drive the development of severe allergic asthma, with a particular focus on the molecular mechanisms through which Th17 cytokines enhance IL-13 signaling, the regulation of the asthmatic response through the PD-1/PD-L axis and the mechanisms of the well-described maternal influence in inherited asthma risk.

Emily R. Miraldi, PhD

Dr. Miraldi is a computational and systems biologist who builds mathematical models of the immune system from high-dimensional genomics measurements. Her studies leverage biotechnologies, including chromatin accessibility and single-cell gene expression measurements, and require new computational methods development. Miraldi’s long-term goal is to use these models to reengineer immune-cell behavior in the context of autoimmune and other diseases.

Chandrashekhar Pasare, DVM, PhD Member, Division of Immunobiology

Chandrashekhar Pasare, DVM, PhD, investigates the mechanisms by which the innate immune system regulates adaptive immune responses. He is also interested in role of Toll-like receptors in innate immunity and inflammation. The overall goal of his research is to provide molecular and cellular insights into how the activation of pattern recognition receptors in cells of the innate immune system induces tailored adaptive immune responses necessary for elimination of specific pathogens.

Tamara Tilburgs, PhD Member, Division of Immunobiology

Dr. Tilburgs’ laboratory investigates how maternal immune cells establish immune tolerance to fetal and placental allo-antigens and remain competent to respond to infections both systemically and in placental tissues.

Ralph E. Vatner, MD, PhD

Radiation therapy is a powerful, non-invasive tool for controlling primary and metastatic tumors in adults and children. However, radiotherapy has two primary limitations: 1) it has limited utility in controlling widely metastatic disease, and 2) it can cause toxic late effects, especially in growing children. Dr. Vatner's research is focused on addressing these two limitations of radiotherapy by studying the effects of ionizing radiation on the immune system.
