In his talk “From Policy to Practice(s) and Practice to Policy: Doing Open Science at Leiden University” Thed will provide both theoretical and practical insights into Leiden University’s approach towards Open Science (OS) – ranging from first steps taken locally at the Centre for Science and Technology Studies (CWTS) more than a decade ago to its more recent involvement in initiatives on the national level, such as the Dutch “Recognition & Rewards” programme, up until present activities at Leiden University and upcoming global trends, issues and challenges within OS.

After Thed’s presentation there will be ample room for discussion – including, e.g., the OS priorities of the BUA which were published in autumn 2025; zooming into lessons learned in Leiden; exchanging views on best practices at Freie Universität and Leiden University etc.

Speaker’s Biography

Trained as a political scientist from the University of Amsterdam, Thed van Leeuwen started working in 1989 at the Centre for Science and Technology Studies (CWTS), a world-leading research institute on scientometrics and bibliometrics, located at Leiden University. In nearly 40 years he has conducted or contributed to about 700 bibliometric studies, most of these in support of research evaluation procedures of any kind, nationally and internationally.

About 15 years ago Thed started specializing in the specific needs that come with research assessment of the SSH and Law domains, writing on issues such as the importance of publication languages, as well as the coverage of bibliographic databases, to serve scholarly domains with his work where it fits, but to also stay away from those scholarly domains where the then research metrics did not fit well, such as the humanities, law and some social sciences.

More recently, being appointed as professor by special appointment on Open Science, under the title “Monitoring Open Science Policies & Practices”, his focus has shifted towards the triangulation of research evaluation, open science, and research integrity/ethics. This academic year, 2025/2026, Thed is appointed as a research fellow of the Berlin University Alliance (BUA).
