The Natasha Chida Lab investigates methods for using education and curriculum development to im...prove patient outcomes worldwide, primarily by optimizing education of physicians-in-training. Most recently, our team has worked to develop and evaluate an assessment tool for evaluating internal medicine residents’ understanding of tuberculosis diagnostics. Previous research includes a retrospective cohort study on the high proportion of extrapulmonary TB in a low-prevalence setting as well as an analysis of ways to define clinical excellence in adult infectious disease practice. view moreResearch Areas: medical education, patient outcomes, internal medicine, tuberculosis

Effective immune responses are critical for control of a variety of infectious disease includin...g bacterial, viral and protozoan infections as well as in protection from development of tumors. Central to the development of an effective immune response is the T lymphocyte which, as part of the adaptive immune system, is central in achieving sterilization and long lasting immunity. While the normal immune responses is tightly regulated there are also notable defects leading to pathologic diseases. Inactivity of tumor antigen-specific T cells, either by suppression or passive ignorance allows tumors to grow and eventually actively suppress the immune response. Conversely, hyperactivation of antigen-specific T cells to self antigens is the underlying basis for many autoimmune diseases including: multiple sclerosis; arthritis; and diabetes. Secondary to their central role in a wide variety of physiologic and pathophysiologic responses my lab takes a broad-based approach to studying T cell responses. view moreResearch Areas: t-cell responses, pathologic diseases, autoimmune diseases, pathology, immune system

The O'Connor Lab studies the molecular basis of infectious disease using Legionella pneumophila... pathogenesis as a model system.Research Areas: infectious disease, Legionella pneumophila, genomics, pathogenesis, molecular biology
We are looking at the network of molecular interactions acting at the host-pathogen interface. Specifically, we use L. pneumophila pathogenesis to examine the numerous mechanisms by which an intracellular bacterial pathogen can establish infection, how it exploits host cell machinery to accomplish this, and how individual proteins and their component pathways coordinately contribute to disease.
We are also studying the role of environmental hosts in the evolution of human pathogens. Using genetics and functional genomics, we compare and contrast the repertoires of virulence proteins required for growth in a broad assortment of hosts, how the network of molecular interactions differs between hosts, and the mechanisms by which L. pneumophila copes with this variation.
