Leah M Schumacher

Assistant Professor
Social and Behavioral Sciences
Ritter Annex Hall Room 945


Dr. Leah Schumacher is an assistant professor in the Department of Social and Behavioral Sciences in the College of Public Health at Temple University. She received her master’s degree in psychology from Drexel University in 2014 and her doctoral degree in clinical psychology from Drexel University in 2019. She completed her predoctoral clinical psychology residency in the health psychology/behavioral medicine track of the Clinical Psychology Internship Training Program at Brown University, followed by an NHLBI-sponsored cardiovascular behavioral medicine T32 postdoctoral research fellowship at the Weight Control and Diabetes Research Center of the Miriam Hospital and the Warren Alpert Medical School of Brown University. Dr. Schumacher then served as an instructor (research) and research scientist at the Weight Control and Diabetes Research Center.

Dr. Schumacher’s research focuses on improving weight loss outcomes and cardiometabolic health among individuals with overweight/obesity and related comorbidities. She is especially interested in enhancing understanding of factors that facilitate (or hinder) regular physical activity among individuals with obesity, and in designing novel behavioral interventions to increase and sustain high levels of physical activity. Dr. Schumacher is also interested in the translation of obesity and physical activity interventions to usual care settings to increase utilization of and ensure more equitable access to health-promoting interventions.
