I am a mathematical biologist interested in infectious disease dynamics and epidemiology. I am currently working on models of hepatitis C virus in populations of people who inject drugs and the impact and cost effectiveness of harm reduction policies and treatment.

Dr Jack Stone is a Senior Research Associate in infectious disease modelling at the Bristol Medical School, University of Bristol. His research focuses on the use of mathematical modelling to project the impact of interventions on transmission of hepatitis C virus and HIV among people who inject drugs.

Has a PhD in mathematical biology and has been working at the University of Bristol since October 2014. At Bristol working on dynamic modelling of hepatitis C in people who inject drugs, modelling current intervention strategies and projecting the impact and cost-effectiveness of treatments and prevention interventions in the future.
