Research Projects

Undergraduate Research Project: Sample Size Rules for Adaptive Clinical Trials , supervised by Prof. Chris Jennison. We proposed a decision rule for interim analyses in clinical trials based on the Bayesian notion of Predictive Power.

Masters Research Project: Machine Learning in Propensity Score Analysis, supervised by Prof. Jen Rogers and Dr Sara Khalid. We assessed the ability of a range of machine learning classifiers to mitigate the effect of selection bias by predicting and then conditioning on the propensity score, defined as the probability of receiving treatment conditional upon observed covariates.

As part of the preparatory first year of my DPhil, I will undertake two 3 month research projects over the summer, the idea being that one of them becomes my substantive DPhil project for years 2-4


I'm interested in learning more about how statistical methods can be applied to biological processes or drug discovery.
