My research concerns algebro-geometric problems arising from physics, in particular, string theory and quantum field theory. My earlier contribution contains a solution to Riemann-Schottky problem in terms of KP equations (1984), and equivalence of dessins d'enfants and Strebel differentials (1998). More recent work deals with quantization and enumerative geometry from the point of view of topological recursion (2010), quantum curves (2016), opers (2018), and geometric theory of topological recursion (2018).
