Summary
I joined the BSU in September 2022 as a Research Associate to work with Sofía Villar on topics around the design and analysis of clinical trials that use digital outcome measures. Previously, I was a postdoc at the London School of Hygiene and Tropical Medicine. I worked with Elizabeth Williamson and James Carpenter on missing data methods in clinical trials that use accelerometers to quantify physical activity. I obtained my PhD from the University of Southampton. My thesis investigated nonmyopic approaches to the design of sequential experiments in the presence of covariates. I was supervised by Dave Woods, Ilya Shpitser and Peter Smith.
