I graduated from Barts and The London School of Medicine & Dentistry in 2010 and subsequently completed training in Nephrology and General Internal Medicine on the North Thames rotation in London. I undertook a Masters degree in Epidemiology at the London School of Hygiene & Tropical Medicine in 2017-19, and returned to commence an NIHR Doctoral Research Fellowship in 2021.

Research

The focus of my research has been to use electronic health records to investigate long-term kidney outcomes after COVID-19 and the economic effects of the pandemic on kidney care. I primarily work on the OpenSAFELY platform, but have also had the opportunity to undertake complementary research in collaboration with the Stockholm CREAtinine Measurements (SCREAM) project based at Karolinska Institutet.
