Prof John Bradley

Prof of Medical Stats & Epidemiology

United Kingdom

I am a statistician and epidemiologist. Most of my work is on malaria and I have a particular interest in cluster randomised trials.

Centres

Centre for Data and Statistical Science for Health
Malaria Centre

Teaching

I organise a short course on cluster-randomised trials. I teach statistics and epidemiology on a range of MSc modules and short courses.

Research

I have worked on a wide range of topics in malaria, including vector control, vaccines, insecticide resistance, bed net durability, housing, malaria in pregnancy, ivermectin, gametocytes, vivax, and mass drug administration.

I have also worked on dengue, HIV, cryptococcal meningitis and fever aetiology.
