Helen Curtis
BSc DPhil
Researcher
I am a postdoctoral health data researcher in the Bennett Institute working on COVID-19-related research in OpenSAFELY, including vaccine coverage and disruption to primary care services. I previously coordinated the development of OpenPathology.net from 2019-2020. I have also worked extensively on the OpenPrescribing project, developing new tools and carrying out research into prescribing patterns in a number of clinical areas.
I previously worked with secondary care and community datasets in a Commissioning Support Unit. I have a DPhil in Genetics from here at Oxford and a Natural Sciences (Cell Biology and Maths) degree from the University of Durham.
