Jon became a student in the Department of Statistics, U.C. Berkeley in 1991 after completing a BS at M.I.T. in 1986. He received his PhD in 1995 under the direction of Steve Evans (me) with a thesis entitled "Capacity of Brownian Trace and Level Sets". He was awarded the Michel and Line Loeve Fellowship to support his outstanding graduate research in probability.
As well as working with me, Jon also collaborated with Yuval Peres and Robin Pemantle on the paper "The trace of spatial Brownian motion is capacity-equivalent to the unit square" that appeared in Probability Theory and Related Fields 106 (1996), 379-399.
