Education and experience

I got my Ph.D. in 2006 from the Center for Operations Research and Econometrics (Université Catholique de Louvain). My supervisor was Prof. Laurence A. Wolsey .
Thesis : ''Integer Programming-based Decomposition Approaches for Solving Machine Scheduling Problems''.

In the same year, I defended my russian Ph.D. thesis ''Algorithms for single machine sheduling problems with the criteria Lmax and wjUj'' at the Dorodnicyn Computing Centre of the Russian Academy of Sciences. My russian Ms. and Ph.D. supervisor was Prof. Alexander A. Lazarev.

During two years (2006‒08), I was a post-doc and a member of the Algorithms and Optimisation team in the Informatics Laboratory (LIX) of the Ecole Polytechnique , where I worked with Philippe Baptiste .
