I am an Assistant Professor at the Department of Computer Science at the University of Helsinki.

I lead the Algorithmic Data Science research group.

Research interests
(1) Algorithms for Efficient Data Science, e..g, model materialization, learned indexes, data summaries. 
(2) Computing with Social Applications, e.g., policy design, web mining.
