Dr. Marion Pepper earned her Ph.D. in immunology in 2006 at the University of Pennsylvania examining the development of the CD4+ T cell response to the eukaryotic parasite, Toxoplasma gondii in the laboratory of Dr. Christopher A. Hunter. She continued to study the adaptive immune response, specifically focusing on memory lymphocyte differentiation and function in Dr. Marc K. Jenkins lab at the University of Minnesota. In 2011, she joined the faculty of the University of Washington Department of Immunology in Seattle as an Assistant Professor. She was promoted to Associate Professor in 2017. The overarching goals of her laboratory are to understand how to regulate immune memory (for both T and B cells) such that anamnestic responses against infections can be optimized, while those against allergy can be suppressed.
