Antoine Aspeel

Welcome!

I am Antoine Aspeel, a CNRS researcher (CR) working on control and optimization. My research interests include safety control, reachability analysis, formal methods and networked control systems.

I am based at CRIStAL, University of Lille (France).

Bio

I was born in Belgium. I received B.Sc and M.Sc degrees in Mathematical engineering at UCLouvain , Belgium.

In 2022, I defended my Ph.D. in mathematical engineering under the supervision of Prof. Raphaël Jungers and Prof. Benoît Macq in the ICTEAM at UCLouvain , Belgium.

After completing my Ph.D., I spent two years as a postdoctoral researcher at the University of Michigan , working with Prof. Necmiye Ozay.

I then spent one year as a postdoctoral researcher at L2S, CentraleSupélec, working with Antoine Girard and Thiago Alves Lima.
