I am a Research Associate with Robert Goudie, working on personal risk prediction models based on electronic health record data. Applications for these models include delirium prediction in ICU environments, and most recently severity modelling of COVID-19. Prior to my work at the Biostatistics unit I obtained my PhD in statistics from the University of Manchester, where I focused on developing new methodology in distribution theory and extreme value theory.
