Research

I am member of the Inria quantum Project team Mocqua, Loria. My main research domain is quantum computing and, more specifically, the study of the complexity properties of quantum programs. I am also interested in:

• Static analysis and verification
• Logic and type systems
• Computational models
• Quantum programming Languages
• Implicit computational complexity

I am currently member of PEPR EPiQ, and of the NEASQC project on next applications of Quantum computing, funded by European Commission REA. I was involved in ACI Criss (2004-2008), ANR Complice (2008-2013), ANR Binsec (2012-2013), ANR Elica (2015-2019) , and ANR SoftQPro. I used to be the principal investigator of the Inria associate team Cristal(2009-2012).

I was in the PC of DICE 2014, FOPARA 2015, RAC 2016, DICE 2018, DICE-FOPARA 2019  and in the OC of CCA 2013.

I was guest editor with Martin Avanzini of a TCS special issue on Implicit Computational Complexity.

I am the principal investigator of the Inria associate team TC(Pro)³(2019-2022).

My Habilitation Thesis has been defended the 19th of October 2020 (online) (Manuscript, Slides).
