RSI's Donald Mattison

Personal Introduction

From my early academic years, the journey through science and medicine seemed inevitable. After obtaining my Bachelors in Chemistry and Mathematics at Augsburg College in Minnesota in 1966, I was off to the Massachusetts Institute of Technology for a Master of Science in Chemistry. My thesis at M.I.T. was entitled: The Design and Construction of an 18 MHz Pulsed Nuclear Magnetic Resonance Spectrometer. A prelude to Magnetic resonance imaging and solid state NMR.

After completing my MS I was drawn to the study of medicine graduating with an MD from the Vagelos College of Physicians and Surgeons at Columbia University, in New York, in spring of 1973. My subsequent clinical training was divided in two with a residency in obstetrics and gynecology at Sloane Hospital for Women at the Columbia Presbyterian Medical Center in New York and a second position as Clinical Associate in Developmental and Reproductive Pharmacology and Toxicology at the Eunice Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, Maryland. These two positions focused on clinical practice and research in risk sciences – with attention to pharmacology and toxicology applied to reproductive and developmental toxicology.

In later years, as I moved to different positions, to continue clinical practice, I obtained medical licenses in six U.S. States including New York (), South Carolina (), Maryland, Arkansas, Pennsylvania and Massachusetts. I would also pursue a desire to serve the nation by joining the U.S. Public Health Service, a uniformed service of the Department of Health and Human Services, ultimately, retiring in 2012 with the rank of Captain (O6).

Professionally, I have been honored with appointments such as Dean, Graduate School of Public Health at the University of Pittsburgh, Medical Director of the March of Dimes, and as the Chief, Section on Reproductive Toxicology at the Eunice Shriver National Institutes of Health in Bethesda, Maryland.

I have also had the privilege of engaging in multiple community service opportunities notably as the Director, Board of Directors and Chair of the Education Committee, Foundation for Advanced Education in the Sciences (FAES), National Institutes of Health, Bethesda MD: 2015 – 2020. I also served as a volunteer physician and Associate Medical Director for the Mercy Health Clinic in Gaithersburg, Maryland. Currently, I am a volunteer physician and Chair of the Quality Improvement Committee for Volunteers in Medicine, on Hilton Head Island in South Carolina.

In 2012, I was excited to join Dr. Krewski and Greg Paoli’s team at Risk Sciences International as Senior Vice-President and Chief Medical Officer.

Most recently, in 2021, I was pleased to accept the appointment as Distinguished Professor of Epidemiology in the Arnold School of Public Health at the University of South Carolina.
