A highly qualified team to work with you

Muriel Shan Sei Fan (President)

Muriel’s been a fan of OCamlPro’s eversince, and decided to dedicate her time to OCamlPro’s team and development, at the side of Fabrice Le Fessant, OCamlPro’s Founder and Scientific shepherd.

Pierre Chambart (CTO and Senior R&D Engineer)

Pierre has a Ph.D. in Computer Science, obtained in the Specification and Verification Laboratory at ENS Cachan. After his PhD, he spent 12 months as an Engineer working on the Ocsigen Web Framework at IRILL, Paris. Finally, he joined OCamlPro in August 2012.

Vincent Laviron (Senior R&D Engineer & Deputy CTO)

Vincent holds a MSc from ENS Ulm, focused on static analysis by abstract interpretation. He then spent several years working on static analysis of functional languages, before joining OCamlPro in June 2015 to work on SecurOCaml.

Raja Boujbel (Senior R&D Engineer)

Raja holds a PhD in software deployment and multi-agent systems from University of Toulouse. Previously, she had studied functional programming and compiler design at Université Pierre et Marie Curie, then worked on the Opa language among MLstate’s distribution team. She joined OCamlPro in March 2018 as a lead maintainer for opam, an open-source package manager for OCaml.

Steven De Oliveira (R&D Engineer)

Steven holds a PhD in formal verification from the Paris-Saclay University and the French Atomic Energy Commission (CEA) since 2018. After a Master in Cryptography he worked in the Frama-C team, developing open-source tools for verifying C programs. He also was involved in science popularization projects like MT180 and InfoSansOrdi.

Guillaume Bury (R&D Engineer)

Guillaume holds a research Master in computer science from Ecole Normale Supérieure in Paris, France, and has studied the integration of rewriting techniques inside SMT solvers during his PhD obtained under the direction of Gilles Dowek and David Delahaye in Deducteam at ENS Cachan. He joined OCamlPro in October 2018 and works in the Flambda team, on optimizations passes for the OCaml compiler.

Adrien Champion (Senior R&D Engineer)

Adrien is interested in formal methods for the verification of safety properties over software and embedded systems. He worked on higher-order functional program verification at the University of Tokyo, in the Kobayashi laboratory, and worked on a predicate-inference tool for horn clauses called hoice, written in rust. Before that, he was working at the University of Iowa on the Kind 2 model checker with Christoph Sticksel and Alain Mebsout.

Keryan Didier (R&D Engineer)

Keryan joined the team in 2020 as a R&D engineer. He holds a PhD from University Pierre et Marie Curie, during which he developed an automated implementation method for hard real-time applications. Previously, he studied functional programming and language design at University Paris-Diderot.

Fabrice Le Fessant (Founder and CSO)

Fabrice founded OCamlPro in 2011 after using OCaml for about 15 years at Inria. His free-software contributions range from improvements in OCaml itself to development tools (OCamlMemprof, ocp-build), distributed software (MLdonkey), blockchains (Tezos, Dune Network, TzScan) and smart contract languages (Liquidity). Former teacher at Ecole Polytechnique, he is a member of the Steering Committee of the Open-Source Hub at Systematic.

Louis Gesbert (Senior R&D Engineer & Deputy CTO)

Louis holds a PhD from University Paris Est, and has studied at EnsIIE, University of Manchester and University of Tokyo. He has a strong background on programming languages and distribution, and was one of the architects behind the Opa language developed at MLstate. He joined OCamlPro in November 2012, and is the lead developer of OPAM. He worked on the learn-ocaml platform and contributes from time to time to the flambda team at OCamlPro.

Thomas Blanc (R&D Engineer)

Thomas used to work as a PhD student between OCamlPRO and ENSTA, with a focus on whole-program static analysis. One of his first objectives is to try to use the whole-program analysis approach to detect uncaught exceptions in OCaml programs. Previously, he obtained a MSc in computer science at the ENS Cachan.

David Declerck (R&D Engineer)

David is a new R&D engineer at OCamlPro. He obtained a PhD from Université Paris-Sud in 2018, during which he extended the Cubicle model checker to support weak memory models and wrote a compiler from a subset of the x86 assembly language to Cubicle.

Laurène Gibaud (Assistant Director)

Laurène joined the team in 2019 to help out with non-tech goals. She holds a technical degree in Web & Network Science and a Master in Publishing Policies. She worked as a publisher and project manager for 5 years on IT & programming publications and has reviewed more than a thousand courses.

Aurore Drombry (Communication Manager)

Aurore joined the team in 2019 to contribute with non-tech goals and optimize internal communication in the organization. She holds a degree in Human Sciences and a Master in Communication techniques & Digital Marketing. Before, she worked for two years as a project manager and communication manager on digital projects.

Léo Andrès (R&D Engineer)

Léo holds a Master’s degree from Paris-Saclay University, focused on foundations of computer science and software engineering. He joined OCamlPro in March 2020 for an internship to study canonical forms and code duplication detection in a mini-ML language. He’s now a PhD student at OCamlPro working on the future garbage collector of WebAssembly.
