Klaus Hulek (born 19 August 1952 in Bad Hindelang) is a German mathematician, known for his work in algebraic geometry and in particular, his work on moduli spaces.
Klaus Hulek studied Mathematics from 1971 at LMU Munich graduating in 1976 with his Diplom. In 1974/75 he studied at Brasenose College of the University of Oxford, where he obtained a master's degree.
As a student he was a member of the Stiftung Maximilianeum and of the German Academic Scholarship Foundation.
He obtained his doctorate under the supervision of Wolf Barth at the University of ErlangenâÂÂNuremberg in 1979. His thesis was "Stable rank 2 vector bundles on with odd first Chern class". In 1982/83, he held a post-doctorate position at Brown University and after that he returned to Erlangen as a research scientist, where he completed his habilitation in 1984, gaining the title Privatdozent.
From 1985, Hulek was a professor at the University of Bayreuth, and in 1990 he moved to Leibniz University Hannover, where he was also vice-president for research from 2005 to January 2015.
In 2015, Hulek was member of the Institute of Advanced Study (IAS) in Princeton, USA He was vice-president of the German Mathematical Society (DMV) from January 2019 to May 2020. Hulek was vice president of the German Mathematical Society (DMV) from January 2019 to May 2020.
During his career, Hulek has been a member of numerous boards and committees. From 1991 to 1993 he was a member of the Struktur- und Berufungskommission of Humboldt Universität zu Berlin (HUB) which had been set up to restructure mathematics at HUB after German unification.
From 2007 to 2014, he was the representative of the German Rectorsâ Council (HRK) at the Research Policy Working Group at the European University Association and from 2009 to 2014 a member of the Committee on European Research Policy of HRK. From 2016 to 2023, Hulek was a member of the Committee for Developing Countries of the European Mathematical Society.ÃÂ
Since 2011, Hulek has been a member of the Foundation Board of the Oberwolfach Foundation, which supports the Mathematisches Forschungsinstitut Oberwolfach (MFO). He is currently a member and deputy chair of the University Council of the Hochschule für Musik, Theater und Medien Hannover (Hanover University of Music, Drama and Media, HMTMH) (since 2024), and a member of the Scientific Advisory Board of EMS Press (since 2025). He was editor-in-chief of zbMATH from 2016 to 2023, during which period zbMATH became the open access service zbMATH Open. Hulek was also editor (2005âÂÂ2012) and editor-in-Chief (2012âÂÂ2025) of Mathematische Nachrichten.ÃÂ

Hulek is a German mathematician, specializing in algebraic geometry, with a particular focus on moduli spaces. He originally worked on vector bundles, moving on to moduli spaces of abelian varieties, Enriques surfaces and K3 surfaces. His work contributed to our understanding of the geometry and topology of moduli spaces and their compactifications.
His earlier results include his work with Barth on monads and moduli of vector bundles and on the Horrocks-Mumford bundle. Together with V. Gritsenko and G. K. Sankaran they proved that all but finitely many moduli spaces of polarized K3 surfaces are of general type.
Hulek has also obtained results on moduli of hyperkähler manifolds and, more recently, on moduli of cubic hypersurfaces, ball quotients and Deligne-Mostow varieties. These results shed light on the interplay between Hodge theory and GIT moduli spaces. His work on the arithmetic of Calabi-Yau varieties, partly with H. Verrill, contributed to number theory and was also taken up in string theory.
