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.)


Organization: PhDay'01, Constructive mathematics, types and exact real numbers, DIAMANT-day '05, Brouwer seminar (from 2004 to 2007), MAP07, Sheaves in Geometry and Quantum Theory, MLNL09, QPL-11, Coq-workshop 2011, MAP11, Type Theory And Formalization Of Mathematics
Homotopy Type Theory and Univalent Foundations - Mini-Symposium at DMV 2015.
CIRM workshop: Computable Analysis: Foundations, Implementation and Certification.
The constructivenews-list.
2018-2021: AFOSR grant: Homotopy type theory and probabilistic computation, 540kUSD. The goal of the project is to apply homotopy type theory to probabilistic programming and to develop theory and tools for computer aided proofs in security.

2015-2019: 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.
