Professor Slava Voloshynovskiy


Slava Voloshynovskiy received radio engineering degree from Lviv Polytechnic Institute in 1993, and Ph.D. degree in electrical engineering from State University Lvivska Politechnika, Lviv, Ukraine, in 1996. In 1998–1999, he has been with the University of Illinois at Urbana-Champaign, USA, as a visiting scholar. Since 1999, he has been with the University of Geneva, Switzerland, where he is a professor with the Department of Computer Science, and Head of the Stochastic Information Processing Group. His current research interests cover the theoretical and application aspects of machine learning, image processing, multimedia and physical world security. He has coauthored over 330 journal and conference papers in these areas as well as 15 patents. He has served as a consultant to private industry in the above areas.
