I used to be a PhD student at the Karlsruhe Institute of Technology. I defended my dissertation in May 2014. Before joining Carsten Dachsbacher's group I received my B.Sc. (2007) and M.Sc. (2009) from the Czech Technical University in Prague with my Master's thesis supervised by Vlastimil Havran. Part of my studies I spent in the US (Union College) and in Singapore (Nanyang Technological University). In the summer of 2011 I worked as an intern at Disney Research Zurich with Wojciech Jarosz and Derek Nowrouzezahrai. I also shortly joined the research team at Pixar Animation Studios as an intern working with Christophe Hery in the summer of 2012.

In August, 2013, I joined the Walt Disney Animation Studios and then moved to Disney Research Zurich in February, 2014.
