Prof. Sławomir Winiarski is the University publishing director and associate professor in the Biomechanics Department at the University of Health and Sport Sciences in Wroclaw, Poland. He teaches academic courses at both the undergraduate and graduate levels in Biophysics, Biomechanics, Biomechanics of Sport, and Clinical Biomechanics. He is an active member of the Polish Society of Biomechanics, the European Society of Biomechanics (ESB), and the European Society of Movement Analysis of Adults and Children (ESMAC). His research interests are in the broad areas of movement science of different human motor activities (e.g., walking, stairs climbing, running, jumping, turning, slopes running, squatting) in sports and physiotherapy and in normal and pathological cases. His current research focuses on using PCA and other discriminant analysis methods to establish multidimensional indexes of movement quality for different movement tasks.
