Research topics

My work revolves currently around two projects:

  • Matryoshka, a project that aims at extending state-of-the-art first-order solvers (SMT & Superposition) to higher-order logic. I am involved in the extension of Superposition to HOL, in the developpement of Zipperposition, in the formalisation of a saturation theorem proving framework in Isabelle/HOL and in improving the CCFV-based instantiation scheme of SMT solvers;
  • CPEC (A3), a projects that aims at producing explications in description logics. I have recently started working on using prime implicate generation in first-order logic to produce such explications.

I have also worked on the derivation reduction of second-order Horn fragments.

Information about my previous research topics can be found on:

that correspond to when I was doing my first post-doc and PhD respectively.
