Research Overview

My research focuses on how aging impact the response to infection. I am an immunologist by training but now have been focusing on the broader impact of infection. This is important since aging is the biggest risk factor for developing disabilities following infections such as influenza. Current work is addressing the impact of influenza infection on physical function and skeletal muscle changes. We are also interested in the impact of cellular senescence and related inflammation on the ability to successfully resolve infection. Finally, we are still also focusing on how aging impacts the immune response to influenza infection, including how senescence impacts the ability of CD4 T cells to respond to virus, clear the virus, and restore homeostasis.
