About me

I am a lecturer in the School of Mathematical Sciences at Adelaide University. I previously worked at CEREMADE, Université Paris Dauphine–PSL; and the Centre for Data Science and School of Mathematical Sciences, Queensland University of Technology.

My research involves designing computationally efficient (sometimes private) algorithms that learn from data with principled uncertainty quantification.

I develop and analyse algorithms for Bayesian inference, including sequential Monte Carlo and Markov chain Monte Carlo. I work with applied scientists to develop principled and robust analysis procedures for their data. This involves designing Bayesian models to incorporate domain and expert knowledge, and developing bespoke algorithms. I also design open source software for statisticians, scientists and industry.

I organised the Adelaide Data Privacy Workshop, held in November 2025. In Paris, I organised the Mostly Monte Carlo Seminar Series. In 2023, I was chair of the SMC Down Under organising committee.
