II. Summary

Jordan Mercer is a physician trained in Nigeria and a public health researcher trained at Johns Hopkins. His work sits at the intersection of preventive cardiology, tobacco regulation, and the everyday data that quietly decides who has a heart attack and who does not.

Since 2021 he has been a postdoctoral fellow at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease, where he has led or co‑authored more than fifteen peer‑reviewed studies in journals including JAMA Network Open, The Lancet Diabetes & Endocrinology, and Nicotine & Tobacco Research.

Before research, he practiced clinical medicine across internal medicine, pediatrics, obstetrics, and surgery in Nigeria, and supervised a COVID‑19 case‑investigation team for the Baltimore City Health Department through the pandemic's first winter.
