I am a lecturer at Swansea University since fall 2021.
I am generally interested in topics around logic, realizability, automata theory and type theory.

Before that, I was a doctoral student at ENS Lyon and at the University of Warsaw,
under the supervision of Colin Riba and Henryk Michalewski, and went on to be a postdoc for two years at
the university of Oxford, working with Michael Benedikt.
My thesis focused on the constructive aspects of Monadic Second Order logic.

## Code

Some things I formalized in Coq.

Ramsey's theorem via H-well-foundedness
link

A formalization of Stefano Berardi and Silvia Steila's paper
An intuitionistic version of Ramsey's Theorem and its use in Program Termination,
exhibiting a theorem analogous to the infinite Ramsey theorem admitting a constructive proof.
The paper introduces the notion of H-well-foundedness for relations, generalizing well-foundedness.
Their main theorem state that this notion is stable under finite union, which leads them to a second
constructive proof of Podelski and Rybalchenko's Termination Theorem.

- An equational theory for Mealy machines link

A little combinator language for letter-to-letter transducers together with a complete equational theory.
This essentially come from the remark that all such transducers correspond to the class of functions between
streams including lifting of maps between alphabets and closed by composition and parametric guarded fixpoints.
