The Division of Population Science serves as a hub for cancer population research within the Sidney Kimmel Comprehensive Cancer Center at Thomas Jefferson University. As part of the Department of Medical Oncology, we work in close partnership with SKCCC research programs, clinical divisions across Jefferson Health, and the College of Population Health to advance behavioral, epidemiologic, data-driven, and community-engaged science. Our faculty bring expertise in behavioral science, epidemiology, implementation science, and outcomes research to accelerate discovery, strengthen cancer care delivery, and reduce the cancer burden across our catchment area and beyond.
