Research Summary:
The current focus of my research is to better understand the biology of how certain risk factors for multiple sclerosis impact the immune system to initiate autoimmunity. To understand the biology of risk, our lab takes the approach of better understanding how specific MS risk factors (including female sex, obesity, cigarette smoking, and head trauma) alter the immune system using lab models of MS. If we understand this biology, it will provide important insights into how the disease gets started, but also may reveal new ways of preventing MS.
Beyond this, we are interested in using animal models of MS as models to study neurological progression to find new ways to slow this process MS.
