Research interests

My research interests are in probability theory, stochastic processes, and their application to large-scale data science problems.

I currently teach the following two courses that I sprinkle with my own interests and examples:

(1) A research-led course that looks at the application of random matrix theory in high-dimensional statistics and machine learning applied to very large datasets. Focus is on understanding how classic approaches break down when the dimensionality of the data becomes large and how these problems may be resolved using recent mathematical results [STAT3017 / STAT7017: Big Data Statistics].

(2) A course on stochastic processes: Markov chains, Brownian motion, their properties and applications [STAT7004: Intro to Stochastic Processes].


Dale graduated from the University of Technology, Sydney (UTS) with a first class Honours in Mathematics in 2006. After his honours, Dale spent some time working in the finance industry. In 2012, he completed his Ph.D. in Mathematics at the University of New South Wales on the topic of Stochastic Partial Differential Equations (SPDE).

Dale has published extensively since 2012 with more than 20 of his papers published in top-tiered journals (A* and A ranked). He has secured more than $2,900,000 in research funding through numerous competitive grants and external funded projects mostly as sole chief investigator.

Researcher's projects

For students seeking Honours or PhD supervision, some keywords to describe my mathematical interests are: stochastic differential equations, stochastic partial differential equations, partial differential equations, Lévy processes, Brownian motion, stochastic processes, random fields, random matrices, high-dimensional probability, random graphs, network theory, dynamics on graphs, high-dimensional statistics, multivariate statistics, statistical learning, machine learning, numerical analysis, numerical methods.

I also like taking these mathematical concepts and using them to solve real-world problems.
