I have been working at LSHTM since 2014, funded by a Medical Research Council Population Scientist Fellowship. My main area of research is in the field of digital health interventions to support sexual and reproductive health. My position is split between the Department of Clinical Research at LSHTM and the graduate school of Tropical Medicine and Global Health (TMGH) at Nagasaki University. 

I completed my PhD titled 'Increasing contraception use with mobile phone-based interventions' at LSHTM in 2017 which included a systemic review of mHealth interventions for contraception and the MObile Technology for Improved Family Planning (MOTIF) trial in partnership with Marie Stopes International in Cambodia.

Previously I completed the Public Health in Developing Countries MSc at LSHTM in 2011 as part of a National Institute of Health Research (NIHR) In-Practice Fellowship based at Imperial College London during 2010-12.

I work as a primary care medical doctor (GP) in London and have worked on an NHS project with Maddox Jolie-Pitt foundation in Cambodia and with Medecins Sans Frontieres in Uganda.
