Research interests

Mathematical physics, theoretical physics, geometry. More specifically I work on supersymmetric field theories, supergravity, and the how these are related via the AdS/CFT correspondence. I'm also interested in geometric structures that arise in string theory and theoretical physics more broadly, notably special holonomy manifolds, Sasaki-Einstein manifolds, and generalized geometry.
