Institute Assistant Director: Dr. Jenna Yentes
PhD, Associate Professor, Director of the Biomechanics Research Laboratory, Dept. of Health & Kinesiology, Texas A&M University.

Dr. Yentes currently serves as the Assistant Director of the Sydney and JL Huffines Institute for Sports Medicine and Human Performance at Texas A&M University. She is also an Associate Professor and the Director of the Biomechanics Research Laboratory in the Department of Health & Kinesiology. Dr. Yentes’ research focuses on the coupling of biological rhythms, such as breathing and walking. Previously, she has explored the clinical utility of breathing and walking coupling for pulmonary rehabilitation in patients with chronic obstructive pulmonary disease. Currently, she is exploring the coupling of biological rhythms for human performance. In addition, Dr. Yentes has published several methods papers regarding the use of tools to analyze fluctuations in human movement data. This allows her the ability to approach human movement analysis from a unique lens adding complementary insights into the field.

Dr. Yentes is a first generation college student, and received her B.A. in Kinesiology from the University of Northern Colorado (2000), M.S. in Kinesiology from California State University Fullerton (2006), and Ph.D. in Biomechanics from the University of Nebraska (2013).
