Assistant Professor

About

I am an assistant professor at Ukrainian Catholic University in Lviv, where I am responsible for conducting research in 3D geometry for computer vision. Previously I worked at the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC) and Facebook Reality Labs Research, where I was responsible for the geometric calibration of head-mounted capture systems. I was awarded the ACCV 2018 Saburo Tsuji Best Paper Award and the IVCNZ 2013 Best Paper Award. I received my PhD in Computer Science from Czech Technical University in Prague.
