Welcome to my academic web page!

You can find here my work in **Logic**
and **Programming**, about the:

- computational content of choice axioms and of completeness theorems;
- meta-theory of intuitionistic logic, such an intuitionistic arithmetical hierarchy;
- formula and type isomorphism, canonical forms of proofs and functional programs;
- type-directed partial evaluation using dependently typed continuations;
- various proof formalizations in Coq and Agda, including one of historical interest: Zermelo's 1904 proof of the well-ordering theorem.
