Research Seminar

Research Seminar of the Group AI and Economics


The seminar is organised by Piotr Skowron and Oskar Skibski. We typically meet every second week and discuss our ongoing projects. You are very welcome to join us or to present your work during our seminar.

We meet on Thursdays at 12:15 in room 4050 at the Faculty of Mathematics, Informatics and Mechanics of the University of Warsaw.

Once per month we are also meeting with a research group from Krakow with whom we are closely collaborating. Our joint seminar is called WKRECAI and you can find more information on it here.
