Health Data Scientist

I am a health data scientist working at the Bennett Institute for Applied Data Science, University of Oxford. My current work centres around the development and use of the OpenSAFELY platform for COVID-19 electronic health record research. My research focuses on NHS service analytics to improve patient outcomes and inform health policy and building tools to support others to do the same.
