I am a Professor of pure Mathematics, specialized in Algebraic geometry, Enumerative and Derived Geometry, and Mathematics of String Theory. I am a Professor at Beijing Institute of Mathematical Sciences and Applications in Beijing, and an Affiliate Faculty Member at IAiFi (Institute for Articial Intelligence and Fundamental Interactions) at MIT. Prior to BIMSA I was a senior personnel at Simons Collaboration Program on Homological Mirror Symmetry at Harvard University Center for Mathematical Sciences and Applications (CMSA) for 7 years, and an Associate Professor of Mathematics at Institut for Mathematik (formerly the Center for Quantum Geometry of Moduli Spaces) at Aarhus University in Denmark. My work is mainly focused on Gromov Witten theory, Donaldson Thomas theory, Calabi-Yau geometries, and mathematical aspects of String theory. I study geometry of moduli spaces of sheaves and curves on Calabi Yau spaces, some of which arise in the study of mathematics of string theory. In my research I have worked on understanding dualities between geometry of such moduli spaces over complex varieties of dimension 2,3,4 and currently I am studying structural properties of such moduli spaces from derived geometry and geometric representation theory point of view. I have also recently become intersted in super algebraic geometry, birtational geometry and bridges between these and enumerative algebraic geometry and moduli theory.
