My research interests focus on the epidemiology of infectious diseases and the use of mathematical models to understand disease transmission and develop control strategies. I joined the HIV Modelling Consortium in February 2014 and I am currently developing hidden Markov models to estimate CD4 progression during HIV infections.
I joined the MRC Centre at Imperial College in January 2011 as part of the Vaccine Epidemiology group led by Prof. Nick Grassly. My research activities involved assessing the impact of oral poliovirus vaccines and inactivated poliovirus vaccines on poliovirus transmission in endemic countries and developing models to inform policy decisions.
Prior to moving to London, I worked with Dr Joseph Wu at Hong Kong University's Department of Community Medicine on antiviral resistance in influenza outbreaks and optimal surveillance strategies. My PhD was based at the University of Liverpool with Drs Steve Paterson and Andy Fenton. The project was a combination of laboratory work, compartmental transmission models and GIS modelling to better understand the impact of long-term climate change on schistosomiasis transmission. Previously, I was involved with the National Malaria Control Programme in Mozambique studying misdiagnosis of malaria in rural health settings.
