Summary

My research involves emerging infectious diseases and focuses on the development of mathematical models to characterise their epidemiology and to evaluate control strategies.

I currently hold a Sir Henry Dale Fellowship funded by Wellcome Trust and the Royal Society to better understand the spatiotemporal dynamics of arboviruses and assess the potential impact of vaccination and Wolbachia, a novel vector control strategy, on dengue transmission and disease.

My research focuses on developing models to integrate data streams from multiple sources and modelling the population-level impact of interventions, as well as better understanding the within-host dynamics of dengue virus and the complex interactions between the serotype-specific antibody responses following natural infection and vaccination. In collaboration with Sanofi-Pasteur, we discovered the fundamental role that pre-exposure to dengue before vaccination has on the vaccine immunogenicity, efficacy and thus on the long-term benefits and risks of CYD-TDV, the Sanofi-Pasteur dengue vaccine.

I am also interested in developing methods and tools to analyse epidemic data from novel emerging infections in real-time. As part of the Imperial College COVID-19 Response Team, I have contributed to the joint efforts to characterising SARS-CoV-2 transmissibility, severity and the impact of non-pharmaceutical interventions. In collaboration with colleagues at the University of Padua (Italy), we found that up to 40% of SARS-CoV-2 infections can be asymptomatic and potentially capable of transmitting the infection but that the timely implementation of interventions can suppress COVID-19. As a member of the WHO Ebola Response Team, I have contributed to the epidemiological characterisation of the Ebola virus affecting West Africa in 2013-2015, which has informed situation awareness and response planning at the WHO. I have also contributed to the characterisation of Zika virus epidemiology and public health implications and developed new methods to assess the risk of international disease introduction during an outbreak.
