I am a physician-scientist with scientific expertise in the pathogenesis of tick- borne Lyme borreliosis in animal models and in humans. This infection can cause a form of chronic inflammatory pauciarticular arthritis that resembles autoimmune forms of arthritis. My research laboratory has contributed to the understanding of the roles of T cells, B cells, and innate immunity in Lyme disease pathogenesis and in prevention of infection. Recent efforts include the application of 2-photon microscopy to study tick-borne infection in real-time. We also conduct translational studies that evaluate human immune responses for the purposes of improving diagnostic tests for tick-borne diseases and understanding variability in outcomes from infection. In addition to research, I care for patients with autoimmune disorders and with complications from tick-borne diseases, supervise rheumatology MD trainees and serve on the fellowship trainee selection committee and on the committee that evaluates fellow research progress. As Associate Dean for Faculty Development & Diversity at YSM, I am responsible for overseeing programs to enhance the careers of a diverse faculty.
