Research Interests

My research focuses on evaluating the mechanisms underlying the development and perpetuation of the most common form of inflammatory polyarthritis: rheumatoid arthritis. Specifically, my group studies the impact of aging on human immune and stem/progenitor cell function. This will help in understanding the interplay of aging with immune tolerance and the risk of developing autoimmune disorders. In addition, we are interested in evaluating how protective responses generated by vaccines can be enhanced in people with rheumatologic conditions. This will help in reducing the morbidity and mortality of vaccine preventable diseases in this vulnerable group.
