Biography

Gilles Stoltz is an associate professeur ETF at HEC Paris, where he has been teaching since 2007 (he is also a senior research scientist at CNRS). He is an alumnus of the Ecole Normale Supérieure of Cachan and holds a Ph.D. and an habilitation diploma from the University Paris-Sud, Orsay, since 2005 and 2011, respectively. 

His research features sequential prediction and sequential decision-making, in the vein of sequential machine learning: adversarial learning (robust aggregation of experts), stochastic bandits, reinforcement learning.
