Biography

I am a PhD student working on software safety applied to artificial intelligence. My research interests include abstract interpretation and symbolic propagation, SAT/SMT solving applied to deep neural networks. I am also interested in the formulation and formalization of specifications for programs using audio and visual inputs.

Interests

  • Software Safety
  • Formal Verification Methods
  • Artificial Intelligence
  • Deep learning

Education

  • PhD in Artificial Intelligence, 2018-2021

    Université Paris-Sud

  • « Diplôme d'ingénieur » (MEng french equivalent), 2014-2018

    ENSTA Paris

  • « Classes préparatoires », 2012-2014

Skills

Python

I am proficient in Python and usual scientific libraries (numpy, scikit, pytorch)

Functional programming

I am writing a medium-sized project in OCaml using the dune build manager. I also have a basic knowledge of Haskell and its type system, as well as Propositions as types

Teaching

I like to teach and learn: I have multiple teaching experience and I enjoy learning, be it on my research topics or something else

Cooking

I am able to blitz a good meal usually vegetarian; I have a strong preference for mediterranean cuisine, but I also like to cook meals inspired by cambodian and japanese cuisine as well

Role-playing and tabletop game

I like to write tabletop RPG stories, and lose my mind watching players inventing completly different stories
