Xin Sun will join he Department of Mathematics at Columbia University as a postdoctoral researcher. He received his Ph.D. in mathematics from the Massachusetts Institute of Technology (MIT) under the direction of Professor Scott Sheffield. Prior to MIT, he received a B.S. in mathematics from Peking University.
Sun is interested in probability theory and mathematical physics. His recent work focuses on understanding the large-scale behavior of two-dimensional discrete objects such as percolation, spanning tree and planar maps, through universal continuum objects such as Schramm-Loewner evolution, Gaussian free field and Liouville quantum gravity.
