E-mail: hjson@uw.edu. Here is my CV.

I’m a fifth-year graduate student in mathematics at the University of Washington. I study probability, combinatorics, and threshold phenomena in random discrete structures, advised by Christopher Hoffman. Previously, I completed a B.S. in mathematics and statistics at Stony Brook University and an M.A. in mathematics at Washington University in St. Louis, where I was advised by Renato Feres.
