I am a postdoctoral researcher at INRIA in Saclay.
My PhD project was supervised by Prof. Dr. Martin Ziegler, Prof. Akitoshi Kawamura and Prof. Dr. Ulrich Kohlenbach and funded by the IRTG 1529.
News:
 04.07.2019: Thanks to all the participants of the "facets of realizability" workshop. You made it a very pleasant experience.
 03.06.2019: The workshop "facets of realizability" which Valentin Blot and I are organizing is coming up! Check out the details on the workshop's webpage.
 02.06.2019: A short version of the paper "Quantitative continuity and computable analysis in Coq" was accepted for presentation at ITP 2019.
Research interests:
 Secondorder complexity theory and its applications to computable analysis
 Computability and complexity theory for partial differential equations
 Formal proofs and program extraction in particular for computation on infinite data
 Weihrauch reducibility and polynomialtime Weihrauch reductions
 Computable analysis based software: iRRAM , AERN, Ariadne etc.
 Connections between real complexity theory, numerical analysis and approximation theory
Software:
 incone: Information theoretic continuity.
 coqrep: Some more experimental extensions of the incone library, currently based on an old version of incone.
 Cheby: Formalization of results about Chebychev approximation.
 iRRAM analytic: An iRRAM library for analytic functions and ODE solving.
Events of interest:
The annual conferences CCA, CCC and LICS.
