About Me


Doctor in High Energy Physics (HEP), I have developed software for a collider experiment called the ILC (International Linear Collider) for many years.

Today I develop software for the industry, as a freelancer.

My work in High Energy Physics had started with my PhD thesis during which I developed a novel particle flow reconstruction algorithm approach based on the tree-like development of electromagnetic and hadronic showers observed in our detectors. This topic implied precise knowledge in HEP but also in scientific computing and in particular in efficient software development.

Then, as a software convener in the ILD collboration, I maintained the ILCSoft framework, the software stack of the collaboration. In addition to the software stack managment, development, maintainance, deployment and user support, I overhauled our main analysis processing software Marlin to take benefit of nowadays incredible hardware power and run data analyses on multi-core machines.

My path led me to the software development for the industry, working for various companies such as Dassault Aviation and Bertin Technologies (ITER project).

Today I develop software as a freelancer.
