Dear colleagues, I am pleased to share with you the Call for Applications for the 9th DHST Dissertation Prize (2027) (attached).

This biennial prize recognizes exceptional doctoral work in the history of science, technology, and medicine. The current competition is open to dissertations completed between 16 April 2024 and 15 April 2026, with applications due by 1 August 2026 (23:59 UTC). A few key points I would like to highlight: Submissions are welcome from any country and in any language, with an English summary. Up to three prizes may be awarded, along with honorable mentions.
