Dr. Potosky is the Director of Health Services Research at Georgetown University, Lombardi Comprehensive Cancer Center. He recently joined the faculty in September 2008. In establishing a national-caliber health services research program as part of the cancer control program at Lombardi, Dr. Potosky will conduct innovative research and build improved research infrastructure to help improve the delivery of high-quality cancer care at Lombardi and nationwide.

Dr. Potosky was recruited to Lombardi after a 21-year career at the National Cancer Institute (NCI), where his efforts focused on dissemination of cancer-related detection and treatment services, and the connection between care delivery and patient health outcomes in diverse populations treated in general clinical practice. He served in the health services and economic branch at the NCI, leading the development of large, extramural initiatives and helping to create data resources to advance the field of cancer-focused health services research. Most recently, he served as the NCI program director for the Cancer Care Outcomes Research and Surveillance Consortium (CanCORS), a national study enrolling more than 10,000 recently diagnosed lung and colorectal cancer patients.

At Lombardi, he will assist with the design and development of the Georgetown Database of Cancer (G-DOC). The G-DOC will initially focus on combining clinical information from patients in clinical trials with molecular characteristics of their cancer. This effort will define the molecular features that underlie prognosis and responsiveness to therapy in patients, providing a basis for personalized medicine and a tool for target discovery and drug development. Looking forward, Dr. Potosky will contribute his expertise to the development of the health services and patient reported outcomes components of the G-DOC.

Dr. Potosky’s research activities at Lombardi will focus on three key themes: measuring care delivery practices and patient-reported outcomes, developing clinic and community-based interventions for improving adherence to best care practices, and measuring the dissemination and long-term adverse effects of established anti-cancer drugs to inform shared decisionmaking.

Dr. Potosky holds a doctorate in health services research and a masters in health finance and management from the Johns Hopkins University Bloomberg School of Public Health.
