My research interests revolve around game theory and statistical learning and their interactions, in particular in the context of security, privacy and ethics of online systems and algorithms. My main current interests are:

  • Ethics of algorithms: transparency, discrimination, fairness (in particular in advertising)
  • Security: adversarial learning, game theory for security, Blotto games
  • Privacy: personal data monetization, learning and privacy
  • Interactions between games and learning: learning in games, repeated games and sequential learning, using the solution of games to analyze/design learning algorithms
Much of my current research aims at studying the interplay between humans or strategic agents and learning algorithms (both how humans impact algorithms through the data they provide or generate and how algorithms impact humans and which consequences it has on algorithms design). I use game theory to model the system and its evolution in order to come up with better algorithms.

In the past, I also worked on causal methods and their applications to networking, cyberinsurance, scheduling and pricing of resources in clouds and smart grids, large deviations and applications to network traffic and to heart-rate modeling, long-range dependence and heavy-tails, and statistical estimation under sampling.
