Researcher in Epidemiology and Statistics
I specialise in developing and communicating statistical methods, software and results for public health protection.
I am a Senior Researcher in the
Pandemic Sciences Institute
at the University of Oxford, working in
Professor Christophe Fraser's group on the CEPI-funded
PRESTO project
which aims to accelerate the start of vaccine effectiveness trials in the event of an epidemic.
From early 2020 I was involved in the motivation, design, maintenance and evaluation of the
NHS COVID-19 app.
A summary of the work can be found
here.
Since its decommission in April 2023, I have continued to be involved in extracting epidemiological insights from the anonymised NHS COVID-19 app data
and advocating for the use of Digital Contact Tracing for mitigation and monitoring of future epidemics.
For this work I was based first at the Oxford Big Data Institute and then in the
Health Protection Research Unit in Genomics and Enabling Data at the
University of Warwick,
working closely with NHS Test and Trace and the
UK Health Security Agency.
My first PostDoc was in the
biomathematics group
at
Imperial College London
with
Caroline Colijn,
where we developed methods and software for comparing
evolutionary trees.
My PhD was in Information Security at
Royal Holloway,
University of London, with
Keith Martin.
I used combinatorial and probabilistic methods to answer questions about
how to distribute cryptographic keys
to secure networks of small devices.
