Current Research

Our lab is interested in identifying novel regulators of inflammation and understanding the molecular mechanisms through which these regulators control innate immunity and the inflammatory response. We are currently pursuing several avenues of research, and they include:

1) Investigating the molecular mechanisms through which different exercise regimens regulate the immune response.

2) Specific targeting of TRAF1 to treat Rheumatoid Arthritis and other inflammatio-driven diseases.

3) Assessing the role of individual Type I interferons in bacterial and viral responses.
