From an Ile‑Ife teaching hospital to a Hopkins lab, by way of the public health front lines.
A practicing physician and postdoctoral researcher at Johns Hopkins, Jordan Mercer's working life moves between epidemiology, preventive cardiology, and a desk piled with tobacco-research preprints.
Mercer trained as a physician at Obafemi Awolowo University in Ile‑Ife, Nigeria, rotating through internal medicine, surgery, pediatrics, and obstetrics before joining the Nigerian Air Force medical service.
He arrived in Baltimore in 2019 for an MPH in Biostatistics and Epidemiology at Johns Hopkins Bloomberg School of Public Health. In 2020 he ran a COVID‑19 case investigation team for the Baltimore City Health Department.
Since 2021 he has been a postdoctoral researcher at the Ciccarone Center under Dr. Michael Blaha — first or co‑author on more than nineteen peer‑reviewed papers in journals including JAMA Network Open and Lancet Diabetes & Endocrinology.
The work, he says, is the slow kind: design a study, clean the data, write it up, defend it at AHA Scientific Sessions. He plans to continue in academic preventive cardiology, with one eye still on the clinical floor.
