Medical research
He is mainly known for his studies on T cells and his pioneering work on chimeric antigen receptors. His work has been the basis of the development of a cancer immunotherapy, involving genetic modifications of T lymphocytes extracted from a cancer patient to produce chimeric antigen receptor (CAR) T-Cells, which are then injected back into the patient in a process called adoptive cell transfer, that produced startlingly good results in clinical trials in the mid-2010s and millions of dollars of investment.
