Biography

Oleksiy Koval received his M.S. Degree in electrical engineering from the National University Lvivska Politechnika, Lviv, Ukraine, in 1996. In 1996–2001, he was with the Department of Synthesis, Processing, and Identification of Images, Institute of Physics and Mechanics (Lviv, Ukraine) as a researcher and Ph.D. student. He received his Ph.D. degree in electrical engineering from the National University Lvivska Politechnika, in 2002. Since 2002, he has been with Stochastic Image Processing Group, Computer Vision and Multimedia Lab, University of Geneva, from which he received his Ph.D. degree in stochastic image modeling in 2004, where he is currently an Assistant Professor.
