I am an Assistant Professor at the Department of Computer Science at the University of Helsinki. I lead the Algorithmic Data Science research group.

(1) Efficient Data Science, e..g, model materialization, learned indexes, data summaries. 
(2) Data Science Applications, e.g., policy design.

To see what kind of research I’m currently interested in, see the articles below:

Short Bio Before Helsinki, I taught at INSA Lyon for one semester (2017) and spent four years (2013-2017) as a postdoctoral researcher at Aalto University. I completed my doctoral studies at the University of Toronto and undergraduate studies at the National Technical University of Athens.
