Since July 2018, I am a Post-Doctoral Fellow in the Logical Systems Lab @ Carnegie Mellon University
My research interests are along the following lines
- reachability analysis and differential dynamic logic
- theorem prover interoperability: HOL4/Isabelle/KeYmaeraX
- formal verification of validated numerical methods, in particular for solving ordinary differential equations
- formalization of mathematics in higher-order logic
- interactive theorem proving
- April 2019: The ARCH 2019 Best Result Award was awarded to my collection of formally verified algorithms for reachability analysis of (nonlinear) systems, HOL-ODE-Numerics.
- December 2018: "Heinz Schwärtzel-Dissertationspreis für Grundlagen der Informatik" was awarded to my PhD thesis.
- August 2018: Best paper and best presentation (by Alexander Maletzky) for Gröbner Bases of Modules and Faugère's F4 Algorithm in Isabelle/HOL at CICM 2018.

I defended my Ph.D. on A Verified ODE Solver and Smale's 14th Problem in May 2018.
Starting in November 2012, I was a Ph.D. student as part of the PUMA graduate school and working on the DFG Kosseleck project Verified Algorithm Analysis. I studied computer science (B.Sc. and M.Sc.), with mathematics as minor subject, at TU München since 2007.
