Since April 2015: Associate professor, Aarhus University

2015: Associate professor at CMU working on the MURI grant Homotopy Type Theory: Unified Foundations of Mathematics and Computation

and Aarhus in the Logic and Semantics Group.

2014: Visiting positions at LRI Paris-Sud, IHP, PPS Paris-7, Gotheburg Computing Science.

2013: Member of the Institute for Advanced Studies for the special year on univalent foundations.

2010-2013: Leading the Nijmegen contribution to the ForMath project, as well as Work Package 4: formalization of exact analysis. (The project got an "excellent" mark.)

**Grant**
Villum Foundation: Guarded Homotopy Type Theory. With Lars Birkedal we received 3.3 Mkr from the Villum Foundation for a research project on Guarded Homotopy Type Theory. The goal of the project is to develop new theories for and prototypes of proof assistants, which can be used within both mathematics and computer science.
