Gene S. Tan, PhD

Assistant Professor

Gene Tan is an assistant professor at the J. Craig Venter Institute working in the Infectious Disease group. The focus of his research is on virus-host interactions by defining the immunological, molecular and genetic determinants that govern immunity and disease. The aim is to better understand how viruses manipulate the host machinery to replicate and in turn elucidate the mechanisms by which the host counteracts the pathogen. Analyses of virus-host interaction can then facilitate the development of better diagnostic tools, novel therapeutics and vaccines.

Prior to his appointment at JCVI, Dr. Tan was a postdoctoral fellow at the Icahn School of Medicine at Mount Sinai working on characterizing the immunological and structural determinants of protection against influenza virus and Zika virus. He received his doctorate from Thomas Jefferson University and his undergraduate degree from the Philadelphia College of Pharmacy and Science.
