Associate Professor
Biography
I am currently assistant professor at Université Paris Dauphine-PSL. I obtained my PhD degree at University Pierre and Marie Curie (Paris) in Algorithmic Decision Theory in the decision team of Lip6 under the supervision of Olivier Spanjaard. After that I was a Postdoc at Gran Sasso Science Institute in l'Aquila. My work falls in the scopes of combinatorial optimization, decision aiding, algorithmic game theory and computational social choice. I enjoy designing exact and approximation algorithms, as well as studying the complexity and parameterized complexity of algorithmic problems. I am interested in a wide range of topics as sequential decision making, voting, allocation procedures and robust optimization.
