Research Assistant
Senior Associate

Aaron recognized early in his medical education that there was a bottleneck in delivering good primary care at the doctor-patient interaction: if a patient cannot implement the doctors’ advice and treatment due to barriers or lack of understanding, the delivery of care is ineffective. Improving this interaction, a type of user-interface, became one of his primary interests through the rest of medical school and into residency, and led to his interest in human factors.

Aaron received his MD from the Icahn School of Medicine at Mount Sinai and began a residency in family medicine at the University of Pennsylvania before transitioning to human factors. He brings his medical knowledge, clinical perspective, and on-the-job experience using many medical devices to his human factors work.

Outside of medicine and human factors, Aaron loves baking, hiking, and traveling.
