About Me

I am a postdoc researcher in IOL group at Zuse-Institut Berlin. I got my Ph.D. at Laboratoire d’informatique de l’École Polytechnique (LIX), where I was part of OptimiX group.

Research Interests

I study mixed integer linear and nonlinear programming, with a special interest in decomposition and cutting plane methods.
