Biography

I am a PhD in computer science specialized in compilers.
I am interested in the design and implementation of programming languages, especially with just in time compilation. I did my PhD in the University of Montpellier under the direction of Roland Ducournau. I worked on a virtual machine for a research Object-Oriented language called Nit. The research was focused on implementing efficiently Object-Oriented mechanisms in the context of a JIT compiler and in multiple inheritance. This was a collaboration with the Université du Québec à Montréal (UQAM) in Montréal, Canada.
Then I worked for one year in the INRIA team CAMUS in Strasbourg, France on automatic parallel optimizations for dynamic languages. We used polyhedral optimizations and tools which are usually used on static languages like C on the JavaScript language. We implemented a proof of concept in the JavaScript Core virtual machine of the webkit project.
Since september 2017 I am a postdoctoral fellow in the Université de Montréal and I worked with Marc Feeley on implementing dynamic languages. I am currently implementing a new just in time compiler for the Python language.
