I am a researcher in computer science at INRIA, in the PARSIFAL team.
My research is about higherorder computation, that approach to computation where the inputs and the outputs of a program are not simply numbers, strings, or compound datatypes but programs themselves. I mainly study the lambdacalculus, using a combination of tools from (linear) logic, graphical syntaxes, rewriting theory, computational complexity, concurrency, formalised reasoning, and implementations of programming languages.
My main achievement (in collaboration with Ugo Dal Lago) is the proof that the lambdacalculus is a reasonable computational model, i.e. that it is polynomially related to Turing machines, see paper [j3] below. Our proof solved a longstanding open problem, and in an unexpected way. The lambdacalculus was indeed suspected to be unreasonable because of a negative result due to Asperti and Mairson (in POPL '98).
I started at INRIA in 2015. My previous affiliations have been:  20132014: P ostdoc at Bologna University, supervised by Ugo Dal Lago; 20122013: Postdoc at Carnegie Mellon University, supervised by Frank Pfenning;
 20102011: ATER at Paris 13 University in the LIPN lab (Villetaneuse, France); 20092010: ATER at Paris 7 University in the PPS lab (Paris, France), during the fourth year of my PhD.
