Dengue Epidemiology

My research aims to improve our understanding dengue epidemiology and transmission dynamics in Asia with a particular focus on serological data and asymptomatic infections.

Modelling Immunity and Infectivity

I am interested in modelling the within-host virus and immune dynamics of infectious diseases. Past work in this area modelled dengue virus and antibody responses during infection, modelling the antibody response after infections, and understanding how individual immune dynamics impact transmission dynamics. Future work in this area will merge antibody and viral data at the individual and population level and expand this work to other arboviruses.

Sero-epidemiology

I am interested in the insights gained from serological data and the importance of asymptomatic infections in transmission and population immunity (work on dengue in this area- see above “Dengue epidemiology section).

Disease forecasting

I have a general interest in disease forecasting using different types of data, how we can understand contact networks relevant to disease transmission and analysis of infectious disease outbreaks.
