Petr Novotný

Postdoctoral researcher in computer science
I am a postdoc at IST Austria, working in the group of Krishnendu Chatterjee. My chief research interests are analysis of probabilistic programs, application of formal methods in AI, and theoretical foundations of probabilistic verification.

I am happy to announce that in September 2018 I am starting my appointment as an assistant professor at the Faculty of Informatics, Masaryk University, Brno, Czech Republic.

You can download my full academic CV here (version from August 2018).
