Postdoc at CREST in ENSAE working with Vianney Perchet as part of the FairPlay Inria team. I have a Ph.D. in applied Mathematics from Université Paris Dauphine and Criteo AI Lab under the supervision of Bruno Bouchard and Marc Abeille.
I am an applied mathematician with interests across Analysis, Probability, and Statistics, specialising in questions of decision theory under uncertainty. I have worked on Control Theory and Reinforcement Learning (including Bandits), Optimal Transport, Hawkes processes, Auction Theory, and more! My research includes a significant interdisciplinary component in Computer Science and Economics. I’m always happy to discuss cool problems, drop me an email.
