Dr Hannah Fraser
MMath, MSc, PhD
Research Fellow in Infectious Disease Mathematical Modelling
Summary
I am an infectious disease mathematical modeller based in Population Health Sciences at the University of Bristol. I am currently working with Professors Peter Vickerman and Matthew Hickman on mathematical models of hepatitis C virus (HCV) and HIV prevention among high-risk populations including people who inject drugs. Specifically, my work focusses on modelling the impact and cost-effectiveness of scaling up prevention interventions and treatment to reduce prevalence and incidence of HCV and HIV.
I completed my PhD in 2015 at the University of Bath. My thesis used several mathematical modelling techniques to examine how the epidemiological dynamics of dengue are affected by interactions between serotypes and age-dependent variation in the extent to which people are exposed to mosquitoes.
