I am an Associate Professor in the School of Mathematics and Statistics at the University of New South Wales, and an Honorary Associate Professor with the School of Mathematics and Applied Statistics at the University of Wollongong. My research sits at the intersection of statistics, computation, and the environmental sciences, with a focus on developing and applying spatio-temporal models to understand complex environmental systems.
I completed my PhD at the University of Sheffield between 2008 and 2011, where I developed variational Bayesian methods for approximate inference in spatio-temporal log-Gaussian Cox process models. This work contributed to early scalable inference methods for complex point process models and was successfully applied to problems in conflict modelling.
Following a brief postdoctoral appointment at the University of Edinburgh, I held an academic position at the University of Bristol from 2012 to 2014, before joining the University of Wollongong in 2014. I joined the University of New South Wales in 2026. Across these roles, my work has combined methodological development, large-scale computation, and interdisciplinary collaboration, particularly in environmental and climate science.

My Research Activities
My research interests lie broadly in spatio-temporal modelling and the statistical and computational tools that enable inference for complex, large-scale systems. I am particularly interested in models that accommodate nonstationarity, non-Gaussianity, multivariate dependence, and massive data volumes, while providing principled uncertainty quantification.
A major focus of my research involves environmental applications. This includes work on assessing Antarctica’s contribution to sea-level rise through the fusion of heterogeneous satellite and observational data, and on estimating the spatio-temporal distribution of greenhouse gas sources and sinks. These projects typically involve large-scale spatio-temporal models, high-performance and GPU computing, sparse linear algebra, and parallel inference algorithms.
More recently, my research has focused on integrating deep learning methods with spatio-temporal statistical modelling. The aim of this work is to leverage the representational power of modern machine learning while retaining the interpretability, structure, and uncertainty quantification offered by statistical models, particularly for environmental and geophysical applications.
My Research Supervision
Areas of supervision
I welcome supervision enquiries from Honours, Masters, and PhD students with interests in spatio-temporal statistics, Bayesian modelling, and statistical machine learning. I am particularly interested in projects that involve methodological development alongside substantive applications in the environmental and earth sciences.
Specific areas of supervision include spatio-temporal and spatial modelling; Bayesian hierarchical models; nonstationary and non-Gaussian processes; multivariate and high-dimensional models; and scalable inference methods, including variational inference, Markov chain Monte Carlo, and neural-network inference methods. I also am keen to supervise projects involving deep learning methods integrated with statistical modelling.
