Saari, Olli

I am a Ramon y Cajal research fellow at the UPC. Previously I have held post-doctoral positions at the Unviersity of Bonn (Germany), Aalto University (Finland) and the Mathematical Sciences Research Institute (the US). I obtained my doctoral degree from Aalto University in 2016 under the supervision of Juha Kinnunen.
