About my research

I work with Chris Holmes and his research group on applied computational statistics focused on biomedical and genomic data. We're particularly interested in the development and application of statistical methods for replicable scientific discovery in biomedicine. The data we work on are typically complex and high-dimensional, comprising a combination of genetic, molecular and clinical data collected on cohorts, often with repeated measurements over time. Methodological areas of current interest include Bayesian sparse factor models, ensemble methods in multi-view learning, and identification of responder subgroups in clinical trials. I also enjoy the application of statistics more broadly, meeting regularly with researchers across the University as part of our Department's consultancy service.
