Michelle Garrison
Primary Investigator she/her/hers
Michelle M. Garrison, PhD is a Professor of Public Health and the Primary Investigator of Purdue University’s Sleep Equity Lab, which focuses on four key research areas aimed at improving sleep and downstream outcomes: 1) harm reduction approaches to late night media use and the impact on sleep, 2) improving our understanding of disparities in time burden as a driver of sleep inequity and potential unintended consequences of interventions, 3) adapting and evaluating sustainable and culturally appropriate sleep behavior change interventions, and 4) optimizing research methods within health behavior change research to increase generalizability, efficiency, and equity of our research approaches.
She earned her MPH and PhD at the University of Washington in the Department of Epidemiology, after previously having received a bachelor’s degree at the University of Texas at Austin in the Plan II Honors program. She grew up in the Midwest, and her first experience in research was working as an intern for two years at the Developmental Psychology department of Northern Illinois University while in high school at the Illinois Mathematics and Science Academy. Her family lives in Texas, and her first public health practice experiences came during college when she worked at the Texas Department of Health on the Oral Rabies Vaccination Project. Prior to coming to Purdue, Professor Garrison was on the faculty of Health Systems and Population Health at the University of Washington, and also worked at Seattle Children’s Research Institute.
Professor Garrison is a member of the Sleep Research Society, the American Academy of Sleep Medicine, and the American Public Health Association, and is an Associate Editor of Sleep Health, the journal of the National Sleep Foundation. She currently teaches an undergraduate course about Sleep and Public Health, and has previously also taught a variety of courses on research and program evaluation methods, statistics, and epidemiology.
