I am the founder and Co-director of the International Centre for Evidence in Disability, a research group at LSHTM that works to expand the research and teaching activities of LSHTM in the field of global disability. I have been working at LSHTM since 2002.

I am an epidemiologist by training. I am passionate about improving health equity for people with disabilities, with a particular focus on people living in Low and Middle-Income Countries. I am an NIHR Global Research Professor and lead a large FCDO-funded grant to investigate how to improve disability inclusion in development. I am also a co-founder of the Missing Billion Initiative.
