My current research interest broadly lies in Applied Probability with a specific focus on Statistical Methods and Monte Carlo Simulation algorithms. In particular, I am interested in Machine Learning, Spatial Point Processes, Perfect Sampling, Large Deviations Theory, and Variance Reduction techniques.

Rare events such as the state-wide power blackout in South Australia in September 2016, natural disasters such as floods and bushfires, or the ensuing chaos when parts of a complex interconnected systems such as the internet fail, are difficult for researchers to simulate or model. They're the primary interest of ACEMS Chief Investigator Dirk Kroese.
