Visiting Researcher







Norfolk PlaceSt Mary's Campus





I am a currently visiting researcher in the Department of Infectious Disease Epidemiology, having been part of the Health Protection Research Unit (HPRU) in Modelling Methodology at Imperial for 4 years.


My research at Imperial is on mathematical and statistical models of sexually transmitted infections in England. The aim is to understand and develop the models for planning and evaluating public health interventions such as screening programmes. My work uses data from clinical studies and national surveillance to understand how infections spread, how disease progresses (natural history), and how levels and rates of infection are related to the patterns detected by surveillance systems. An improved understanding will help with putting in place the most effective and best-value interventions possible.

Other Academic InterestS

I am currently employed as a teaching fellow in the Centre for Applied Statistics Courses at UCL.

I am part of a collaboration looking at the epidemiology, transmission and control of Epstein-Barr virus.

From 2009 to 2015 I conducted doctoral and postdoctoral research at UCL into paediatric HIV infection and immunological development.
