Research

The objective of Dr. Paulos' research is to develop novel T cell-based therapies for patients with melanoma. Her laboratory seeks to identify mechanisms underlying protective immunity in solid tumors, with an emphasis on adoptive T cell transfer (ACT) therapy. By combining basic and translational understanding of human T cells in clinical studies with mechanistic studies in relevant mouse models and in investigator initiated clinical trials in patients, her research team has contributed significant insight into the various roles of how to mount T cell memory responses to tumors.
