Research Interests:

  • Equilibria in static games, repeated games, incomplete information games, and continuous-time games.

  • Learning in repeated interactions, with complete or incomplete information.

  • Information economics and competitive equilibrium.

  • Various topics in mathematical economics, game theory, microeconomic theory, real analysis, and others.

Works in Progress:

  • Slicing the Nash Equilibrium Manifold

  • Equilibrium in Unidimensional Insurance Markets w/ Coverage Restrictions (w/ Andre Veiga, tentative title)

  • Bayesian Equilibrium: From Local to Global (w/ Ziv Hellman and Dov Samet, tentative title)

  • Undecidability of Existence of Measurable Equilibrium Selections

Works in Early Stages (titles tentative):
