I am an Assistant Professor in the Centre on Climate Change and Planetary Health. In 2023 I was the lead author on the Lancet Pathfinder Commission Report entitled 'Pathways to a healthy net-zero future: report of the Lancet Pathfinder Commission'. At the School I am a Co-I on the Wellcome Trust funded Pathfinder Initiative, which aims to assess and synthesise lessons from the implementation of practical, evidence-based pathways to zero-carbon societies. My role in Pathfinder involves working with institutional partners, including C40 Cities, SDSN, OECD, CDP, AFIDEP and APHRC, to design and deliver policy relevant research aimed at filling knowledge gaps on the co-benefits of greenhouse gas mitigation actions – namely which actions, when implemented, have the largest multiple benefits for health, the environment and prosperity. I am also PI on the UKERC funded WinWindow project which aims to assess the feasibility and data challenges to monitoring and tracking co-benefits in health, environment, jobs and energy from UK net zero policies.

Before I worked at LSHTM I was the Executive Secretary to the Rockefeller Economic Council on Planetary Health at Oxford Martin School and part of the Secretariat of The Rockefeller Lancet Planetary Health Commission. In 2015 I was lead author on the Rockefeller-Lancet Planetary Health Commission report entitled 'Safeguarding human health in the Anthropocene epoch: report of The Rockefeller Foundation–Lancet Commission on planetary health'. I have a background in conservation biology and macroecology and have worked on biodiversity indicators in both terrestrial and marine systems, including for the WWF Living Planet Index, which tracks trends in the status and abundance of the world’s vertebrate biodiversity. I am an expert contributor to many international reports, including the 2019 IPBES Global Assessment and as a reviewer for GEO-7. I am a member of the steering committee for the 2024 What Works Climate Solutions Summit, a major global conference on evidence-based policy for climate solutions.
