Eligible to supervise Masters and PhD - email supervisor to discuss availability.


I am a Senior Lecturer in Statistics at the School of Public Health. My expertise lies in Bayesian approaches to quantifying uncertainty, risk and in developing methods for better decision-making. 
 
I am interested in Bayesian methods for decision-making, uncertainty and risk quantification. My research is motivated by the need to bridge the gap between research and practice. I seek to develop decision-making frameworks that are practical yet grounded in the mathematical and philosophical aspects of Bayesian inference. My current research focus is on expert (prior) elicitation and robustness, and on quantifying the risk and uncertainty in possible decisions.  Majority of my research is motivated by real-life applications, which are currently Health and cyber-risk. 
In the past, I have worked on statistical modelling problems in diverse areas such as Crime Science, Ecology, Engineering, Market research, Pharmaceuticals, Psychology, and Sports science. 
 Prior to starting my position at the University of Adelaide in 2025, I was at the Department of Statistics at the University of Auckland (NZ) and prior to that, at the Department of Mathematics, University of Waikato (NZ). 
Prior to my PhD at the Trinity College Dublin (IE), I worked as a Statistician on clinical trials for BMS and Novartis in Mumbai (IN).
