My current interests are in Bayesian methodology and applications relating to the analysis of mixture models and hidden Markov models, particularly when the number of components therein is unknown. My PhD focuses on a comprehensive suite of methods for modelling such situations using overfitted models which are able to deal with the myriad issues arising from overfitting. Key concepts include the mixing ability of MCMC samplers, and dealing with the label switching problem.
Personally, I am driven by one main goal: to simplify the complex and provide tools to improve our understanding of the world around us. I am particularly interested in developing innovative methods which can be used in or adapted for a broad range of applications, supplying tools which are able to be used and understood by those actually employing them in practice. I aim to create useful, logical tools for complex data analysis, which can contribute to the way we process and understand the ever increasing amount of information available around us.
I am experienced with the program R .
- Development of new methodology
- Mixture models
- Hidden Markov Models

Most of my work is based on the development of new methods and is theoretical or simulation-based. I am actively working on
- Overfitting Mixture models
- Overfitting hidden Markov models
- Label Switching
- Parallel Tempering
- Overfitted VS Non-Parametric mixture models
I am also currently involved in a collaborative project with the CSIRO working on finding subgroups in the controls of an Alzheimer’s research study. This will complement the larger goals of their program, aiming to identify control individuals at risk of having either been misclassified as healthy controls, or who may have developed Alzheimer’s during the course of the study.
