Profile

R. Gul Tiryaki Sonmez is Professor and the chair of the Department of Exercises Sciences and Recreation at Lehman College, The City University of New York. She is also the director of Exercise Science Program in the Department of Exercise Sciences and Recreation. She has a Ph.D. from the University of New Mexico, USA; an M.S. from Oklahoma State University, USA, and a B.S. from Sport Academy, Ankara, Turkey. Her diverse research interests include studying the impact of exercise on appetite hormones, the effects of ergogenic aids in sports and athletic performance, and the practical applications of exercise biomechanics. In addition, she is involved in the prevention of childhood obesity and the promotion of fitness in the general population as a means to improve health and wellness. She has taught many courses and developed undergraduate and graduate programs in the area of physical education and sport and exercise sciences. She has also served in a variety of administrative positions including Vice President of Academic Affairs, Director of the School of Physical Education, and Chair of Training Sciences and Physical Education Department. She has written two books on exercise physiology, which are still being used as text book at universities throughout Turkey. She also has authored 4 book chapters and about 60 peer-reviewed articles. Furthermore, she has chaired 18 theses and co-chaired many others. She is currently a chief and a regional editor of the two International journals and a peer reviewer for 7 different scientific journals.
