Short Bio
I am a tenured associate professor at Aalto University, and a research scientist at NVIDIA Research. Prior to that, I spent a few years as a postdoc with Frédo Durand at MIT. I work on computer graphics and computer vision, in particular realistic image synthesis, appearance acquisition, and procedural animation.
Prior to my research career, I worked for the game developer Remedy Entertainment in 1996-2005 as a graphics programmer, and contributed significantly to the graphics technology behind the worldwide blockbuster hit games Max Payne, Max Payne 2, and Alan Wake.
In my free time, I enjoy rock climbing, photography, cooking, and music (e.g. singing).

I had the honor to be elected Teacher of the Year 2013 in the Computer Science Degree Program at Aalto, and received the Aalto University School of Science Teaching Award in 2018. Also, both my introductory and advanced computer graphics classes have been chosen by the students to be among the Best Computer Science Classes at Aalto every year I've given them. In addition, I've helped Prof. Jukka Suomela to design and teach his multiple award-winning Programming Parallel Computers class.
