RESEARCH INTERESTS
Dr. Ostendorf’s work integrates epidemiology, exercise physiology, psychology, and dissemination and implementation (D&I) science to design, optimize, and evaluate lifestyle intervention programs for adults. She engages potential adopters using human-centered design testing methods to design programs that fit patient’s needs. She has been funded by the NIH and the American Heart Association (AHA) for the past 8 years and currently has a NIH Career Development Award to engage potential adopters from multiple levels to co-design a physical activity support program for adults with overweight or obesity. Her long-term career goal is to prevent and treat chronic diseases by designing and disseminating theory-based, optimized lifestyle interventions that promote sustained behavior change. She is passionate about helping adults improve their health and wellbeing in ways that approachable and sustainable.
ADDITIONAL INFORMATION
Prior to joining faculty at UTK, Dr. Ostendorf was an Assistant Professor at the University of Colorado Anschutz Medical Campus (CU-AMC) in Aurora, CO in the Division of Endocrinology, Metabolism, and Diabetes. Dr. Ostendorf received her PhD in Epidemiology at the Colorado School of Public Health and completed four years of a postdoctoral fellowship with Victoria Catenacci, MD’s lab where she learned to conduct large-scale clinical trials focused on evaluating the effectiveness of novel lifestyle interventions. As a postdoctoral fellow, Dr. Ostendorf was one of 15 researchers across the world to receive the Endeavour fellowship, where she worked with Neville Owen, PhD, and David Dunstan, PhD studying the adverse effects of too much sitting at the Baker Heart and Diabetes Institute located in Melbourne, Victoria, Australia. Dr. Ostendorf is actively involved in the Society of Behavioral Medicine (SBM), the Obesity Society (TOS), and attends the Academy Health’s Annual Conference on the Science of Dissemination and Implementation.
