projects at the Harvard T.H. Chan School of Public Health. First, he joined the HQSS Commission, which culminated in a comprehensive report on healthcare system quality in 134 low- and middle-income countries. Afterwards, he conducted research at the department of Health Policy and Management, primarily working on comparing costs, outcomes and quality for Medicaid and heavily-subsidized private health insurance for low-income individuals and buprenorphine policy to tackle the opioid crisis. A unifying theme in Dennis’s work is the use of rigorous research to shed light on healthcare systems and policy on vulnerable populations. Dennis graduated with a degree in Economics and Statistics from UC Berkeley in 2016 and has since conducted analyses using methods found in epidemiology, biostatistics, econometrics, and machine learning. He has also published in journals such as The Lancet Global Health, Health Affairs, BMJ Open and Health Services Research. For fun (and pre-COVID), Dennis is a martial artist, having competed on UC Berkeley’s Taekwondo sparring team, and training in Brazilian Jiu Jitsu. |
