Advice for (prospective) students
Important! Read this before contacting me on potential student exchanges etc.

Bill Freeman's excellent notes on how to do research
Frédo Durand's fun notes on writing.
Kayvon Fatahalian's advice for CMU CS students. Applies to everyone ambitous here too.

I am a tenured associate professor at Aalto University, and a principal research scientist at NVIDIA Research. I work on computer graphics, computer vision, and machine learning, with particular interests in generative modelling, realistic image synthesis, and appearance acquisition and reproduction. Overall, I'm fascinated by the combination of machine learning techniques with physical simulators in the search for robust, interpretable AI.

Prior to taking my current positions, I spent 2007-10 as a postdoc with Frédo Durand at MIT. Before 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 (2001), Max Payne 2 (2003), and Alan Wake (2009).

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.
