I am currently a Ph.D. student at Paris Sud University, working in the ParSys group at Laboratoire de Recherche en Informatique (LRI).

My thesis focuses on power-aware population protocols and stochastic optimization problems, under the supervision of

Joffroy Beauquier, Janna Burman and Abdel Lisser.

My research interests include :

  • population protocols
  • energy problems in mobile wireless sensor networks
  • self-stabilizing distributed algorithms
  • chance constrained program (stochastic optimization)
