Name of Hiring Official/Investigator

Job Description

The Surgery Branch at the National Cancer Institute functions as a multidisciplinary research group with the goal of developing novel immunotherapies and immunotherapeutic strategies for cancer. The Surgery Branch was responsible for the development of multiple immunotherapy advances over the years, including interleukin-2 (IL-2), the first effective immunotherapy in humans, and the development of cellular immunotherapies (TIL, TCR, and CAR) against solid cancers and hematologic malignancies.

The current position is for a postdoctoral fellowship in the lab of Dr. Sri Krishna within the Surgery Branch. The main focus of the group is to utilize the branch’s rich repository of samples including human tumors, patient-derived neoantigen T cells, and associated samples, to ask questions in human immunology and tumor immunology, with the ability of applying basic discoveries for rapid translation in our ongoing cell therapy clinical trials.

Research projects range from experimental immunology, computational biology, to basic T cell biology, tumor evolution, immune resistance by metastatic human tumors, epigenetics, clinical immunology, and gene engineering of T cells. The successful candidate will have the chance to contribute to cutting-edge research projects aimed at advancing cancer immunotherapies and understanding the molecular and cellular mechanisms underlying T cell-mediated responses against human cancers.

About the NCI Center for Cancer Research

The Center for Cancer Research (CCR) is home to nearly 250 basic and clinical research groups located on two campuses just outside of Washington, D.C. CCR is part of the National Cancer Institute (NCI) and makes up the largest component of the research effort at the National Institutes of Health (NIH). Centrally supported by long-term funding and a culture of complete intellectual freedom, CCR scientists are able to pursue the most important and challenging problems in cancer research. We collaborate with academic and commercial partners and advocacy groups across the world in efforts to prevent, diagnose and treat cancer and HIV/AIDS. The CCR research portfolio covers the full spectrum of biological and biomedical research. Our work ranges from basic to translational and clinical, and our clinical trials are conducted in the NIH Clinical Center, the world’s largest hospital dedicated to clinical research that offers a robust infrastructure to support CCR’s patients on an estimated 250 open studies. The success of CCR is grounded in an exceptionally strong discovery research program that provides the foundation for the seamless translation of insights from bench to bedside.
