Welcome

I'm a Post-Doc Post-Doc with Assia Mahboubi, at Inria Nantes.

Here's a short CV (Jan. 18).

My research interests lie at the interface of Logic, Type Theory and Functional Analysis. I am interested in continuous models of computations, and their applications to differential equations.

News:

• With Guilhem Jaber, we're organizing a reading group on differentiable programming.
• I will participate to Bellair's workshop on higher-order probabilistic computation in March 2019.
• I will speak at SYCO in Oxford, also in March 2019. This is a friendly and non-competitive meeting, consider submitting !
• I will participate to ETAPS 2019 , in Prague, 6-11th April.
• I will speak at the Big Proof workshop 2019 , in Edinburgh, May 27th-31st.

Preprints

• Models of Linear Logic based on the Schwartz ε-product , with Y. Dabrowski, 82 pages, submitted in april 2018.
• A formalisation of Hahn-Banach theorem in Coq , with Assia Mahboubi. Submitted short abstract corresponding to a formalization of Hahn-Banach theorem in Mathcomp + axioms.

Published Papers

• Higher-order distributions for Differential Linear Logic , with J.-S. Lemay, accepted for publication at Fossacs 2019 (conference).
• A Logical Account for Linear Partial Differential Equations , 2018, accepted for publication at LICS 2018 (conference).
• Mackey-complete spaces and power series - A topological model of Differential Linear Logic , with C. Tasson, 2018, Mathematical Structures in Computer Science (journal).
• Weak topologies for Linear Logic, 2016, in Logical Methods for Computer Science (journal).

In preparation

• Polarization in topological vector spaces, based on Chapter 6 and Chapter 2.5 of my thesis

Thesis

• I defended my PhD thesis on October 19th 2018. You will find here the manuscript and the slides .
