Research summary
Chimeric antigen receptor (CAR) T cell therapy has revolutionized treatment of B cell leukemia and lymphomas. However, over half of the patients receiving CAR T cell therapy ultimately have their disease progress. This failure is largely due to imprecise CAR signaling.
In Nathan Singh’s lab, I am working on engineering the signaling domain of CARs to prevent T cell dysfunction and improve tumor clearance of CAR T cells. Currently, I am generating experimental wet lab data to be used in downstream deep learning applications for CAR engineering. Ultimately, I hope to develop a CAR capable of more robust T cell activation leading to increased cytotoxicity, proliferation, and persistence than current CARs.
