Nicolas was born in Washington, D.C., and grew up in Beirut, Lebanon. He graduated from Princeton University in 2017 with a B.A. in Public Policy and a minor in Global Health and Health Policy. As an undergraduate, he worked as a research assistant to study polypharmacy and associated health risks in older adults. Following graduation, he worked to augment health capacity and reduce shortages of essential medications in a rural public hospital district in South Africa through the novel use of an existing mobile technology platform. He is currently a third-year student at Harvard Medical School, where he has advocated for lowering barriers to treatments for opioid use disorder as a member of the Student Coalition on Addiction. As a DPM fellow, he is working with Dr. Frank Wharam and Dr. Anita Wagner to assess the impacts of high-deductible health plans (HDHPs) on diagnostic delays in metastatic cancer in the United States. His overarching research aim is to examine how health systems - in particular insurance designs and cost barriers - delay or limit access to essential care.
