### Research

The research expertise of Motohico Mulase lies in the interplay of many areas of mathematics, such as algebraic geometry of moduli spaces of Riemann surfaces and Higgs bundles, nonlinear integrable systems such as KP and KdV equations, Gromov-Witten theory, and topological recursion. His research accomplishments include a solution to the Schottky problem (a characterization of Jacobian varieties) in terms of KP equations (Novikov conjecture) **[1]**, establishing the solvability of soliton equations and supersymmetric generalizations **[2]**, discovery of the equivalence between Strebel differentials and Grothendieck's dessns d'enfants **[3], **a proof of the Bouchard-Mariño conjecture on Hurwitz numbers **[4]**, and a solution to the conjecture of Gaiotto** **on conformal limit and opers of Beilinson and Drinfeld **[5]**.
