Originally trained as a biologist, I completed my MSc in Control of Infectious Diseases at LSHTM in 2004. Prior to joining the Environmental Health Group, I have been involved in household water treatment projects in Peru, the Dominican Republic and India and worked in infectious diseases surveillance at the HPA Centre for Infections, London.
