Defining the Transcriptomic and Epigenetic Reprogramming of Human Tumor-Infiltrating CD8 T Cells After PD-1 Blockade


Cancer Research Institute - Mark Foundation Postdoctoral Fellow (2019-2021)

Josephine Giles, PhD

Dr. Giles is determining how blocking the signals that inhibit T-cell function causes reprogramming at the epigenetic level resulting in more effective cytotoxic function.
