Biography

I am an Assistant Professor in Statistics at Universiti Brunei Darussalam, the leading higher education institution in Brunei. My research interests lie in statistical theory, methods and computation, with a special inclination towards social science applications.

I obtained my PhD in Statistics from the London School of Economics and Political Science (LSE) in October 2018. My PhD project explored the use of Fisher information-dependent priors in a vector space framework for regression, classification, and variable selection. My supervisors were Dr. Wicher Bergsma and Prof. Irini Moustaki. I also obtained an MSc in Statistics from LSE in 2014.

I graduated from Warwick University, completing the 4-year MMORSE degree in 2010. As my final year project, I used Bradley-Terry models applied to English Premier League football data. This project was supervised by Prof. David Firth.

Previously, I was a Research Officer at the Centre of Science & Technology, Research & Development (CSTRAD), Ministry of Defence, Brunei. My primary task was to provide data analysis and decision support to strategic acquisition projects, and assist in statistical analyses for defence-related research.

Oct 2010 – Sep 2019 Brunei
I provided analytical insight into matters arising from the development and activities of strategic procurement projects for the Royal Brunei Armed Forces (RBAF). This entailed market research, cost-benefit analyses, and writing technical reports. I was a project team member for the procurement and delivery of 12 Sikorsky S-70i helicopters (US$325M), and also the focal point for the development of tender evaluation criteria using the Analytic Hierarchy Process (AHP). After completing my PhD, I conducted various research into defence-related activities.
