Dr. Cary Gross is a Professor of Medicine and Co-Director of the Robert Wood Johnson Foundation Clinical Scholars Program at Yale. Dr. Gross completed his residency in Internal Medicine at New York Hospital - Cornell Medical Center and served as chief medical resident at Memorial Sloan-Kettering Cancer Center the following year. He completed the RWJ Clinical Scholars Program at Johns Hopkins School of Medicine in 1999.

The over-arching theme of his work is the disconnect between evidence generated from clinical research and the needs of members of patients in the "real-world" setting, outside of clinical trials. He has received NIH-funded grants explore barriers to clinical trial enrollment, the impact of non-cancer illnesses on older persons with cancer, and the dissemination of new cancer screening and treatment modalities into clinical practice. After documenting that older persons are disproportionately excluded from clinical research, Dr. Gross also demonstrated that applying trial results to patients who were above the age limit of trial eligibility was associated with a higher risk of harm. These findings led to work addressing the impact of non-cancer health conditions on quality of care, preferences, and outcomes. Ongoing investigations focus on the comparative effectiveness of different approaches to cancer screening and treatment, and how effectiveness is moderated by age and comorbidity.
Bioethics and research integrity are also a major interest for Dr. Gross. His work has focused on issues affecting research integrity, as well as access to research studies and experimental agents.
