In January 2023, I joined UCL's Department of Science, Technology, Engineering & Public Policy (STEaPP) as Professor of Research Policy, from where I'm also Director of the Research on Research Institute (RoRI), which I co-founded in 2019 with a mission to accelerate transformative research on research systems, cultures and decision-making. RoRI's consortium now includes research funders and scholarly communication organisations from 15 countries, who between them invest over US$25 billion each year in R&D. 

Since the late-1990s, as a researcher, writer, adviser and campaigner, I've worked at the heart of science and research policy in the UK and internationally. In addition to academic posts at the universities of Sheffield, Sussex and Lancaster, I've worked in think-tanks, NGOs and as director of science policy for the UK's national academy of sciences.

In my work, I've advanced concepts such as upstream public engagement, science diplomacy, responsible metrics and responsible research assessment; and I've co-founded or led initiatives such as People & Planet; the Campaign for Social Science; the International Network for Government Science Advice (INGSA); the UK Forum for Responsible Research Metrics; the Royal Society Science Policy Centre; and the Research on Research Institute (RoRI).

In 2014, I was invited to chair an independent UK government review of research metrics, published as The Metric Tide. I subsequently chaired a European Commission expert group on Next Generation Metrics, and in 2022, with Stephen Curry and Elizabeth Gadd, revisited these debates in Harnessing the Metric Tide.
