Saul Jacka's research is in many areas of probability theory with special interests in mathematical finance, stochastic processes, stochastic control, optimal stopping, conditioned processes and probability on trees and related structures.

Professor Jacka is currently Editor-in-Chief of the international journal Stochastics.
