Brief Biography

Kristen graduated with a bachelor’s degree in Biological Sciences from Cornell University in 2006, where she was a varsity rower and a biology student advisor. She graduated with an MPH from the University of North Texas Health Science Center in May 2008. While studying for her master’s degree, Kristen was Vice President of the Public Health Student Association, a teaching assistant for Principles of Epidemiology and Intermediate Epidemiology, and a fellow in the Minority K-12 Initiative for Teachers and Students program. After graduating, Kristen worked as a research coordinator at the Primary Care Research Institute in Fort Worth for two years.

In 2010, Kristen entered the Epidemiology doctoral program at Boston University School of Public Health. As part of her internship, she conducted an analysis of maternal use of CNS medications in relation to neurocognitive outcomes in 5-12-year-old offspring. Kristen graduated in 2014. Dr. Hahn completed a two-year postdoc in the Department of Epidemiology at BUSPH where she worked on a study of treatment for opioid addiction in pregnancy and two prospective cohorts of pregnancy planners based in North America and Denmark. Currently, Dr. Hahn is a Senior Epidemiologist at Quintiles and is based in Cambridge, Mass.
