About Me

I am a second-year DPhil student in the Department of Statistics and the Oxford-Man Institute of Quantitative Finance at the University of Oxford. I previously completed an MSc in Statistics (2022–2023) and a BSc in Mathematics and Statistics for Finance (2019–2022) at Imperial College London, where I developed a strong interest in statistical modelling and quantitative finance. Before beginning my doctoral studies, I worked as a Market Risk Analyst at JPMorgan Chase (2023–2024), where I gained valuable insights into the practical challenges of quantitative finance. My current research focuses on asset pricing anomalies and the effects of real-world trading frictions.

Emma Prevot

Health Data Science CDT student

About Me

I am a DPhil student on the Health Data Science CDT working on statistical and generative machine learning for causal inference, with emphasis on applications to neuro-imaging data. Prior to starting the DPhil, I completed a BSc in Physics with Medical Physics at University College London (UCL) followed by an MPhil in Machine Learning and Machine Intelligence at the University of Cambridge.

Rik Knowles

DPhil in Statistics student

About Me

I am a first-year DPhil student researching efficient data acquisition through an information-theoretic lens, with a focus on Bayesian Experimental Design (BED) and Active Learning (AL). My work aims to improve the scalability of BED and AL, addressing computational bottlenecks such as sampling in high-dimensional parameter spaces (e.g. images), or the combinatorial complexity of searching over possible batches in AL.

Looking ahead, I’m also interested in exploring others areas including generative modelling, and Bayesian optimisation.

Dr Younjung Kim

Postdoctoral Researcher

About Me

I am a postdoctoral researcher within the Oxford Martin School’s Digital Pandemic Preparedness programme, supervised by Professor Christl Donnelly and Professor Moritz Kraemer. 

Building upon my background in Veterinary Medicine and postgraduate training in Epidemiology, my research has primarily focused on understanding the transmission dynamics of animal and zoonotic infectious diseases, including avian influenza, African swine fever, and Rift Valley fever.

Research Interests

My current research explores the integration of diverse epidemiological data sources, including digital data streams, to improve our understanding of the complex dynamics underlying infectious disease transmission.
