Deborah J. Fowell, DPhil


Principal Investigator

Professor and Chair, Department of Microbiology & Immunology

Director, Cornell Center for Immunology

Dr. Fowell assumed her position as Professor and Chair of the Department of Microbiology and Immunology in October 2020. Previously, she was Dean’s Professor in the David H. Smith Center for Vaccine Biology and Immunology and the Department of Microbiology & Immunology at the University of Rochester Medical Center. where she had worked since 2000.  

She received a B.Sc. degree in Cellular Pathology from Bristol University in the UK in 1988 and was awarded a Ph.D. (rather a D.Phil.) in immunology from University of Oxford in 1992. She performed postdoctoral studies at the Oxford Sir William Dunn School of Pathology and at University of California, San Francisco in the Infectious Disease Division.


Dr. Fowell's work fills a niche in the Cornell immunology community, bridging fundamental immunology and cellular and tissue imaging. Her research program continues to be supported by funding from the National Institutes of Health.

Scott A. Leddon, PhD


Senior Research Associate

As the Senior Research Associate in the Fowell Laboratory, Scott functions as the lab’s go-to for experimental planning, technical implementation, and data analysis.


His primary research focus is to understand how temporal and microanatomical cues within the germinal center impact the ability of T cells to effectively help B cells. Spatiotemporal cues controlling the germinal center reaction represent an attractive immunomodulatory target to either enhance protective antibody responses to pathogens or to diminish antibody-mediated autoimmunity. 


Scott completed his Ph.D. at the laboratory of Andrea Sant where he worked on understanding the antigen-specificity of T follicular helper cells after vaccination. He then worked as a postdoctoral fellow in the laboratory of Jim Miller where he identified a dimerization domain within CD28, before joining the laboratory of Deborah Fowell in 2017. As a postdoctoral associate in the Fowell lab, Scott identified a critical role for alpha-v integrin expression by CD4 T cells for the generation of long-lived plasma cells.


In October 2020, Scott moved with Deborah Fowell to the Department of Microbiology & Immunology in the College for Veterinary Medicine at Cornell University in Ithaca, NY.
