Richard and Barbara Schiffrin President's Distinguished Professor

Dr. E. John Wherry the Barbara and Richard Schiffrin President’s Distinguished Professor, Chair  of  the  Department  of  Systems  Pharmacology  and  Translational  Therapeutics in  the Perelman School of Medicine and Director of the UPenn Institute for Immunology.  Dr. Wherry received his Ph.D. at Thomas Jefferson University in 2000 then did postdoctoral research at Emory  University  with Dr. Rafi  Ahmed  from  2000-2004.Dr.  Wherry  has  received  numerous distinctions and honors including the Distinguished Alumni award from the Thomas Jefferson University,  the Cancer Research Institute’s Frederick W. Alt  Award for  New  Discoveries  in Immunology and the Stand Up To Cancer Phillip A. Sharp Award.  Dr. Wherry has over 225publications. He has an H-Index of 101and his publications have been cited over 55,000 times. 

Dr. Wherry’s research  has pioneered the  field  of  T  cell exhaustion –the  fundamental mechanisms by which T cell responses are attenuated during chronic infections and cancer.  His  discoveries helped identify  the  role  of PD-1and  the  ability  to  block  this  pathway to reinvigorate exhausted  T  cells.His  group  also  first  demonstrated that targeting  multiple co-inhibitory  receptors  simultaneously  could synergistically  improve  therapeutic  efficacy,  a foundation for current combination immunotherapy efforts in humans. Dr. Wherry’s work has defined the transcriptional and epigenetic atlas of exhausted T cells defining exhausted T cells as a distinct immune lineage.  Finally, his laboratory has been a pioneer in defining the concept of Immune Health using systems immunology approaches, most recently applying this concept to COVID-19.
