I am a postdoctoral researcher at Université of Montréal inside the S2M Lab working with Mickael Begon on biomechanics and predictive simulation. Before that, I was a Ph.D student at Ecole Normale Superieure de Rennes, with Charles Pontonnier and Georges Dumont. I am passionate about understanding and modeling human movements. Thanks to my Ph.D in biomechanics, I want to address scientific questions such as the muscle forces, fatigue modelling, population-based biomechanics, optimal design of assistive devices, and anatomical joint modelling.

|---|---|---|---|
| Bioptim | Python | A Python library for biomechanics optimal control, integrating Acados and Ipopt solvers, with my leadership in theoretical developments and coordination. Published in IEEE Transactions. | GitHub |
| CusToM | MATLAB | Contributed to a MATLAB toolbox for musculoskeletal analyses and model personalization during my PhD, with user customization and modularity. Published in the Journal of Open Source Software. | GitHub |
| BioNC | Python | Initiated and led the development of BioNC for biomechanics dynamics in natural coordinates, facilitating model creation and analysis. | GitHub |
| CocoFEST | Python | Functional electric stimulation optimal control, based on Bioptim framework, addressing dynamic modeling and fatigue behavior. More to come with @kev1co. | GitHub |
| Majority-judgment | Python and Rust | Led an initiative to follow public opinion, according to majority judgment, an alternative voting method, during the French presidential campaign of 2022. I collected data from public opinion polls and presented monthly developments to the association members. More recently, I led the implementation of the voting system in Rust Language. | Link1, Link2 |
