Research Degree Student

I’m a public health specialty registrar, doing an MRC-funded doctorate on the epidemiology and modelling of typhoid as a basis for vaccine programme decisions. I have been working with the World Health Organization on vaccination against Ebola, including epidemiological needs assessment and a novel ring vaccination trial.

Before joining the School, I coordinated the preparations of the UK Health Protection Agency national infectious disease surveillance centre for the London 2012 Olympic and Paralympic Games, and worked at the Department of Health immunisation policy branch.

After qualifying as a pharmacist from the University of Nottingham and Bart’s & London hospital trust, I did my clinical residency at Guy’s & St Thomas’ Hospitals, providing 24/7 pharmaceutical care for acutely-ill patients and developing prescribing guidelines for the hospitals and across the local area.  I then moved into NHS public health specialty training, working in health service commissioning, local government health improvement programmes and communicable disease control.

I have taught various aspects of public health, including infectious disease epidemiology, vaccine implementation and disease screening, at LSHTM, UCL, KCL Brighton & Sussex Medical School and Cambridge. I am also involved in training of public health registrars, including for membership exams of the Faculty of Public Health.


My doctoral research aims to inform the design of vaccination programmes and other interventions for the control of typhoid fever, particularly in the Pacific region, such as through school-based immunisation or child and adult vaccination campaigns.

In 2013, I did six months of fieldwork in Fiji in collaboration with the Ministry of Health, WHO Western Pacific, University of Queensland (UQ), other health partners and many volunteers who generously gave their time and blood samples. This cross-sectional, population-representative survey aims to determine exposure to Salmonella Typhi infection through the study of immune system antibodies. This, alongside data on social mixing, is intended to inform transmission dynamic modelling for vaccine decisions.

The serum survey has also been used for investigation of leptospirosis, led by Colleen Lau of ANU, and is banked for use in investigation of dengue fever (collected shortly before a large-scale outbreak of dengue-3) and other arbovirus research with Adam Kuscharski (LSHTM) and Pacific partners.

I also have developed a strong research interest in Ebola, in responsing to the tragic events in West Africa. I am currently collaborating on a vaccine clinical trial, Ebola epidemiological research and transmission dynamic modelling.
