I am now an Assistant Professor at Boston University. My research interest mainly falls in the interplay between Enumerative Geometry, Differential Geometry and Mirror Symmetry.

I am co-organizing the BU Geometry & Physics Seminar with Brian Williams this year, meeting every Wednesday 4--5pm. Feel free to join us or email me if you are interested to give a talk! My research is supported by NSF standard grant DMS-2204109 and also a Simons Collaboration grant.# Student Supervised
