Welcome to my (mostly) research homepage.
I am Associate Professor at the Department of Computer Science in University of Helsinki and Institute for Atmospheric and Earth System Research (INAR). I am Vice Director of Helsinki Institute for Information Technology HIIT. I have a PhD in theoretical physics and I hold a title of docent in information and computer science (tietojenkäsittelytiede).
Please also see my research group homepage. My old research homepage is for time being archived for historic interest. You can also find (at least links to) miscellaneous material, including some historic web pages created by me.
(We are always looking for good people, please contact me if interested!)
