Prof. Marcus Vieira is the Bioengineering and Biomechanics Laboratory head at Universidade Federal de Goiás. He received BS in Electrical Engineering and Physical Education from the Universidade Federal de Goiás, and MSc and PhD in Biomedical Engineering from the Universidade de São Paulo. He focuses his research in computational neuroscience and biomechanics, especially in motoneuron modeling, spinal CPG, nonlinear tools for movement variability analysis, including entropy, fractal dimension and recurrence analysis, coherence analysis in postural control, transitory tasks such as gait initiation, and gait dynamic stability.
Songning Zhang (PhD & FACSM) is a professor of biomechanics and the director of the Biomechanics/Sports Medicine Laboratory at the University of Tennessee, Knoxville. He is a fellow of American College of Sports Medicine and a member of American Society of Biomechanics, International Society of Biomechanics, and China Sport Science Society. He is a visiting professor at the Shanghai University of Sports and at the Nanjing Sports Institute, China. His publications include work appearing in biomechanics, sports science, medical journals, and book chapters. He is currently an associate editor and editorial board member for Journal of Sport and Health Science, and an associate editor for Research Quarterly for Exercise and Sport, and an editorial board member of PeerJ. He has reviewed manuscripts for many academic peer-reviewed journals, including the Medicine & Science in Sports & Exercise; Journal of Biomechanics, Gait and Posture, Clinical Biomechanics, Arthritis Care & Research, etc.
