Academic Bio

Karen Schliep, PhD, MSPH is an assistant professor in the Division of Public Health. She completed her bachelor's degrees in English from Carleton College (Northfield, MN) and Biology from the University of Utah and her MSPH and PhD in Public Health from the University of Utah. Dr. Schliep completed her pre-doctoral and post-doctoral fellowship at the Eunice Kennedy Shriver National Institute of Child Health & Human Development (NICHD) Epidemiology Branch, where she served as an integral team member of several longitudinal studies including the BioCycle Study, the Endometriosis: Natural History, Diagnosis, and Outcomes (ENDO) Study, and the Effects of Aspirin on Gestation and Reproduction (EAGeR) Trial.

Dr. Schliep's research focuses on exploring the impact of diet, lifestyle, and psychosocial factors on female and male endocrinology and reproductive health; and understanding the short-and long-term consequences of abnormal reproductive function. Her overarching goal is to inform effective and individually tailored interventions for couples of reproductive age, which in turn may provide improved wellbeing and economic benefits for future generations.
