Jaroslav Křivánek Associate Professor (doc. Ing., Ph.D.) Faculty of Mathematics and Physics Charles University, Prague Malostranské náměstí 25 118 00 Praha 1, Czech Republic (map) CV | Google Scholar | publons | orcid.org

Prof. Jaroslav Krivanek passed away on December 1st 2019

I am an associate professor of Computer Science at the Faculty of Mathematics and Physics of Charles University, Prague (known as "Matfyz"), where I co-lead the Computer Graphics Group. I am also a co-founder of and the Director of Research at Chaos Czech a.s. (formerly Render Legion a.s.), the company behind the realistic rendering software Corona Renderer, now part of Chaos Group. Previously, I was a Marie Curie research fellow at Cornell University working with Kavita bala, and a researcher at Czech Technical University in Prague (working with Jiří Žára), as well as at University of Central Florida (working with Sumanta Pattanaik). I got my Ph.D. from INRIA Rennes and CTU Prague (joint degree, co-advised by Kadi Bouatouch and Jiří Žára).

My primary research interest is in computer graphics, with the focus on realistic rendering, light transport simulation, Monte Carlo methods, and computational fabrication/3D printing. I enjoy industry collaboration and the technologies I've co-developed have been employed, among other, by Weta Digital, PIXAR, Chaos Group, Allegorithmic, etc. The desire to see my reasearch results used in practice led me to co-founding in 2014 the company Render Legion, where I now serve as Director of Research. In 2014, I was selected for New Europe 100, “a list of outstanding challengers who are leading world-class innovation from Central and Eastern Europe”.
