Dr. Larry Ryan, Physicist
Research Engineer
University of Texas at Dallas, Ph.D. Experimental Physics, 1988

Dr. Ryan completed his Ph.D. in experimental physics from the University of Texas at Dallas in 1988 and was involved in research projects for both the physics and biology departments. He was supported by NASA to develop ultraviolet spectroscopy systems for the measurement of oscillator strengths for highly ionized atoms. He also was involved in the biology department's research in photoreactivation and he implemented a spectroscopy system to study the way in which photoreacting enzymes repair damaged DNA by inducing ultraviolet light.

Dr. Ryan has developed an extensive career as an industrial physicist and has designed a wide variety of instrumentation, robotics, and control systems for laboratory, industrial, military, and biomedical applications. He has developed biomedical equipment for a number of companies, including Abbott Critical Care Systems, Alcon Laboratories, Baxter International, Essilor Laboratories, and Transitions Optical. He also has developed magnetic resonance instrumentation for NASA and the National Science Foundation.  


Dr. Lindsay Wohlers, Exercise Physiologist
Research Associate
University of Maryland, Ph.D. Kinesiology, 2012

Dr. Wohlers joined the lab in July 2012 after completing her Ph.D. in Kinesiology at the University of Maryland, College Park, where she also completed a Master’s degree in 2008. Prior to Maryland, Dr. Wohlers received a B.S. in Movement Science from the University of Michigan in 2007. For her graduate studies she was supported by a training grant through the National Institute of Health. Throughout both her Master’s and Ph.D. programs, Dr. Wohlers’ research was centered on metabolic regulation at the cellular level. Specifically, she investigated alterations in adipose tissue and skeletal muscle which occur in response to changes in ovarian hormone levels, research which is of particular importance for post-menopausal women and women undergoing breast cancer treatment.

With a desire to continue studying metabolism, but at a whole body, rather than cellular level, Dr. Wohlers joined the Locomotor Performance Lab in July of 2012. Her research currently focuses around the factors which influence energy expenditure during walking and running.


In addition to pursuing degrees in Kinesiology, Dr. Wohlers has also put her knowledge into action through her involvement in triathlon. She has completed multiple Ironman races since 2008 (2.4 mile swim, 112 mile bike, 26.2 mile run), with numerous age group wins and a course record in the mix. She has raced in the World Championships in Kona 5 times and will be racing as a professional starting in 2013.


Ken Clark
Doctoral Student
Swarthmore College, B.A., 2003
West Chester University, M.S., 2009

Mr. Clark joined the Locomotor Performance Laboratory as a doctoral student in August of 2010, after serving as the Director of Performance Training for Summit Sports Training Center in West Chester (PA) where he was responsible for the speed, strength and conditioning training of professional athletes from the National Football and National Hockey Leagues in addition to high school and collegiate athletes.  Mr. Clark has completed coaching internships with both Villanova University and the Philadelphia Eagles. 

Mr. Clark completed his undergraduate degree at Swarthmore College in Swarthmore, Pennsylvania, where he was an All-Conference and record-setting running back.  In 2009, he completed a master's degree at West Chester University of Pennsylvania with a research focus on sprint biomechanics. 

Mr. Clark brings extensive applied knowledge on the mechanical basis of training and performance and rigorous academic training at the undergraduate and master's levels to the doctoral program at SMU.  His doctoral research focuses on the mechanical basis of sprint exercise performance.
