Since 2002 I have worked in global health policy. Initially I focussed on drug and vaccine research and development, and access to medicines. Over time, this has broadened to cover antimicrobial resistance, epidemic and pandemic response, planetary health (including the impact of environment and climate change on health), digital health and AI for health, and many more. Although I am based academically at the University of Oxford, my initiatives and work are with colleagues and institutes located all over the world.

In recent years I have brought together large groups of colleagues around major global health challenges that no one group on its own can solve and that require cross-disciplinary and trans-disciplinary collaboration.

Increasingly I am interested in the way we do ‘global health’, recognising the need for greater equity in the research process and in access to the fruits of research, the need for a radical redistribution of power within global health governance structures, and better evidence-based decision making to achieve more rapid and lasting practical real-world impact.

I have worked extensively with students and early-career researchers, lecturing and teaching on several graduate courses, supervising and examining student projects and dissertations, organising and funding small projects, and supporting a growing network of early-career researchers and future leaders.
