Chris Klebanoff, M.D.
Dr. Klebanoff is cellular immunologist and medical oncologist with 24 years of experience in the pre-clinical and early clinical development of T cell-based immunotherapies for the treatment of cancer. Prior to joining Memorial Sloan Kettering and the Parker Institute for Cancer Immunotherapy in 2016, he was a Howard Hughes Medical Institute Research Scholar and Assistant Clinical Investigator at the National Cancer Institute in Bethesda, Maryland.
Dr. Klebanoff pioneered the paradigm that T cell subsets with the memory-like attributes of self-renewal and multipotency are a critical determinant for adoptive immunotherapy efficacy. Further, he resolved how host lymphodepletion – a standard practice for nearly all cellular immunotherapies – enhances the potency of adoptively transferred T cells through the removal of homeostatic cytokine “sinks.” The Klebanoff laboratory is currently focused on the discovery and immunologic targeting of shared neoantigens resulting from recurrently mutated driver genes using TCR gene therapy.
Clinically, Dr. Klebanoff has contributed to the successful early phase development of numerous T cell-based therapies. These include an anti-CD19 chimeric antigen receptor (CAR) that would become FDA approved (Yescarta®), tumor infiltrating lymphocyte therapy for the treatment of melanoma (Lifileucel) and other common cancers, and TCR gene therapies targeting epitopes derived from NY-ESO-1 (Letetresgene), MAGE-A3, and HPV16.
Dr. Klebanoff is an elected member of the American Society for Clinical Investigation and recipient of several prestigious awards, including the Damon Runyon Clinical Investigator Award and a National Institutes of Health MERIT Award. Multiple technologies developed in his laboratory have been licensed to biotechnology companies and was a scientific co-founder of Affini-T Therapeutics.

Tom Wandless, Ph.D.
Tom Wandless, Ph.D., is Obsidian’s Scientific Founder and a Professor of Chemical and Systems Biology at Stanford University. Dr. Wandless earned his Ph.D. in chemistry from Harvard University and his B.S. in biochemistry from Trinity University. Following his undergraduate studies, he worked in the laboratory of Stuart Schreiber where he helped elucidate the molecular mechanisms of the immunosuppressive drugs, FK506 and cyclosporin. Based on those studies, he then developed the first chemical dimerizer system to control specific gene transcription in T cells. He spent two years as a postdoctoral fellow with Chris Walsh at Harvard Medical School before starting his own lab at Stanford in 1995. The Wandless Lab concentrates on the invention of molecules and techniques that enable better studies of biological processes, inventing tools and techniques that provide new experimental windows into mechanisms that cells use to maintain protein homeostasis. In particular, his work over the last 15+ years on the use of small molecules to regulate protein folding and stability serves as the basis for Obsidian’s Drug Responsive Domain technology.
Tom Wandless, Ph.D.
Tom Wandless, Ph.D., is Obsidian’s Scientific Founder and a Professor of Chemical and Systems Biology at Stanford University. Dr. Wandless earned his Ph.D. in chemistry from Harvard University and his B.S. in biochemistry from Trinity University. Following his undergraduate studies, he worked in the laboratory of Stuart Schreiber where he helped elucidate the molecular mechanisms of the immunosuppressive drugs, FK506 and cyclosporin. Based on those studies, he then developed the first chemical dimerizer system to control specific gene transcription in T cells. He spent two years as a postdoctoral fellow with Chris Walsh at Harvard Medical School before starting his own lab at Stanford in 1995. The Wandless Lab concentrates on the invention of molecules and techniques that enable better studies of biological processes, inventing tools and techniques that provide new experimental windows into mechanisms that cells use to maintain protein homeostasis. In particular, his work over the last 15+ years on the use of small molecules to regulate protein folding and stability serves as the basis for Obsidian’s Drug Responsive Domain technology.
