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 vsiting 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 analysis of entire chain of multimedia processing starting from the data acquisition and interaction with physical objects to the final end-users. It includes optimal design of imaging systems (sparse antenna arrays), processing (denoising, restoration), storage (compression, feature extraction) and communication (coding) as well as security and privacy related issues of information sharing, search, identification, authentication, classification and mining in large scale-systems. The main focus is on the information-theoretic and machine learning aspects of the above problems.

He has coauthored over 250 journal and conference papers in these areas as well as 12 patents. He has served as a consultant to private industry in the above areas.
