Welcome to the Homepage of Jan Křetínský

Since October 2015 I am a tenure-track assistant professor at the Chair for Foundations of Software Reliability and Theoretical Computer Science, Technical University of Munich, Germany.

Education and previous positions

From 2013 to 2015 I was an IST Fellow at IST Austria hosted by the group of Thomas Henzinger and the group of Krishnendu Chatterjee.
I received my PhD at the Technical University Munich, Germany, where my advisor was Javier Esparza. The thesis Verification of Discrete- and Continuous-Time Non-Deterministic Markovian Systems was defended summa cum laude (with distinction). I received another PhD at Masaryk University Brno, Czech Republic, with my advisor being Antonín Kučera and my thesis Modal Transition Systems: Extensions and Analysis (with distinction). There I also received my Master's and Bachelor's degrees in computer science, mathematics, philosophy and linguistics.
My CV can be found here.

Aalborg University (computer science department and CISS), Denmark
(one semester in 2009, one month in 2011, two weeks in 2014),
INRIA Rennes, France
(three weeks in 2012, two weeks in 2014),
Saarland University - Computer Science , Saarbrücken, Germany
(one week in 2013, one week in 2015).
