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 was appointed Assistant Professor in 2005 in the Immunology Program at The Wistar Institute and then joined the Department of Microbiology in the University of Pennsylvania’s Perelman School of Medicine in 2010. He became the Director of the Institute for Immunology in 2012 and Chair of the Department of Systems Pharmacology and Translational Therapeutics in 2018. Dr. Wherry has received numerous distinctions and honors for his consistent and significant contributions to immunology, infectious disease and cancer research 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 190 publications in top international journals. He has an H-Index of 87 and his publications have been cited over 43,000 times. Dr. Wherry’s research has pioneered the field of T cell exhaustion – the fundamental mechanisms by which T cell responses (and likely those of other immune cells) are shut off or attenuated during chronic infections and cancer. His discoveries helped to identify the role of the “checkpoint” molecule PD-1 and the ability to block this pathway to reinvigorate exhausted T cells. His group was also one of the first to demonstrate 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 also created the transcriptional and epigenetic atlas of exhausted versus functional T cell biology and this atlas of information has led to numerous mechanistic discoveries that helped define exhausted T cells as a distinct immune lineage. Finally, his laboratory has been a pioneer in using transcriptomics, high dimensional cytometry, and systems immunology approaches to study immune oncology, human vaccine responses and human infectious disease. Ongoing work in his laboratory focuses on applying transcriptional, epigenetic, single cell and systems immunology approaches to study exhausted T cells and other immune cells in health and disease.

Padmanee Sharma, MD, PhD.

Padmanee Sharma headshot
Dr. Sharma is a nationally and internationally renowned physician scientist who is a pioneer in the field of immune checkpoint therapy. In 2006, Dr. Sharma designed and conducted the first neoadjuvant (pre-surgical) clinical trial with immune checkpoint therapy. She designed and conducted multiple clinical trials, which eventually led to FDA-approval of immune checkpoint therapy for cancer patients, including patients with bladder cancer as well as patients with renal cell carcinoma. She conducted key experiments to define biologic pathways that are involved in anti-tumor responses, including ICOS + effector T cells and tertiary lymphoid structures. She also performed innovative studies to define mechanisms of resistance to immune checkpoint therapy, including loss of signaling in the IFN-pathway, VISTA, and epigenetic pathways such as EZH2. In addition, she identified organ-specific immune responses that contribute to resistance of bone metastases to immune checkpoint therapy. Her detailed laboratory studies have allowed her to design and implement rational combination clinical trials to overcome resistance mechanisms. Currently, Dr. Sharma focuses her effort on a “reverse translation” process that encompasses studies on human immune responses to generate hypotheses related to mechanisms of tumor rejection, which she tests in appropriately designed pre-clinical models, and subsequently uses the new data to design novel clinical trials to improve outcomes for patients with cancer. She is the inaugural Scientific Director of the Immunotherapy Platform, Professor in the Departments of Genitourinary Medical Oncology and Immunology, the T.C. and Jeanette Hsu Endowed Chair in Cell Biology, and Co-Director of Parker Institute for Cancer Immunotherapy at M. D. Anderson Cancer Center. She is a member of the American Society for Clinical Investigation (ASCI); received the Emil Frei III Award for Excellence in Translational Research in 2016; the Coley Award for Distinguished Research for Tumor Immunology in 2018; and honored with the Women in Science with Excellence (WISE) award in 2020.

Christopher Hunter headshot
Christopher Hunter is recognized as an international leader in the role of cytokines in the induction of innate and adaptive immunity to infection, as well as their role in the resolution of inflammatory processes. His collaborative studies with the academic and biotechnology communities over the last 25 years on the IL-12 family members has helped to define their role in the induction of cell mediated immunity that have been broadly relevant to many types of inflammatory processes. For example, his discovery that IL-27 was a potent inhibitor of cell mediated immunity has formed the basis for work on its therapeutic potential in cancer and autoimmunity and continues to be a focus of the laboratory. Professor Hunter obtained his Ph.D. at the University of Glasgow, Britain and a post- doctoral fellowship at Glasgow developed his interest in the role of cytokines in immunity in the CNS. This was followed by a postdoctoral fellowship at Stanford University working on Toxoplasma, before joining the faculty at the University of Pennsylvania. There his research group continues to study the cytokines that influence innate and adaptive immunity to parasitic infections.
