I am Associate Professor (computer science and atmospheric sciences) at the Department of Computer Science in University of Helsinki. I am affiliated with Institute for Atmospheric and Earth System Research (INAR) and I am a Vice Director of Helsinki Institute for Information Technology HIIT.

I have a PhD in theoretical physics (University of Helsinki, 2001). I hold a title of docent in information and computer science (tietojenkäsittelytiede) at the School of Science of Aalto University, Finland.

Even though my doctoral thesis was about particle physics, I have been for over a decade interested in computer science and especially data analysis. My primary interests lie in the areas of data mining, machine learning, artificial intelligence, and related algorithms.

I am especially interested in explorative data analysis, in being able to make analytic decisions with the help of large heterogenous data sources, and in introducing new methods and computational concept into other sciences and application areas. Computation is the new common language for sciences, just like mathematics. The technology has however been available only for a relatively short time. Many of the fundamental concepts and methods have therefore not been yet invented, which makes this an exciting field to work in.
