KU Leuven invites applications for several PhD positions in Pure Mathematics, funded by the long-term Methusalem program. The positions are part of the collaborative research project "Classification, symmetries and singularities at the frontiers of algebra, analysis and geometry," which brings together expertise from multiple research groups to tackle challenging problems in algebra, analysis, and geometry. The project covers a broad spectrum of mathematical research, including algebraic and arithmetic geometry, random matrices and complex analysis, differential geometry, functional analysis and operator algebras, as well as algebraic topology and group theory. Special consideration is given to candidates interested in interdisciplinary work bridging two or more of these areas. PhD students will join a vibrant academic environment with regular colloquia, seminars, and advanced courses, fostering collaboration and exposure to diverse mathematical topics. All PhD students will have limited teaching duties. KU Leuven is committed to improving gender balance and diversity within its pure mathematics research groups and strongly encourages applications from underrepresented groups. Applicants should hold a master's degree in mathematics or an equivalent qualification, with a strong research interest demonstrated by their master thesis. Master students who expect to graduate before August 2026 are also eligible. Fluency in English is required; Dutch is not necessary. The positions offer a competitive four-year PhD stipend, funding for conference participation and short research stays at other institutions, as well as health insurance and social benefits for the student and their accompanying partner and/or children. The starting date is flexible, preferably before 1 October 2026. To apply, candidates must submit an online application including three PDF files: a motivation letter, a curriculum vitae (listing three references, master thesis topic, tentative graduation date, and any preprints or publications), and transcripts of bachelor and master studies. References will be contacted only for shortlisted candidates. Applications can be withdrawn and resubmitted until the deadline. For further information, contact Prof. dr. Karel Dekimpe at [email protected]. KU Leuven fosters an inclusive, respectful, and socially safe environment, embracing diversity as an asset and striving for equal opportunity. The university does not tolerate discrimination based on gender identity, sexual orientation, age, ethnicity, skin colour, religious or philosophical beliefs, neurodivergence, disability, health, or socioeconomic status. Accessibility and support inquiries are welcome via the provided contact email. For more details on the research topics, visit the project website: Methusalem Pure Math Research Lines .

KU Leuven is offering several postdoctoral positions in pure mathematics, funded by the long-term Methusalem program. The positions are part of the collaborative research project "Classification, symmetries and singularities at the frontiers of algebra, analysis and geometry," which brings together expertise from multiple research groups to tackle challenging problems in algebra, analysis, and geometry. The research environment is highly stimulating, with regular colloquia, seminars, and advanced courses, and offers broad exposure to diverse mathematical topics and collaboration opportunities. The postdoctoral researchers will develop their own research programs in pure mathematics, with particular interest in candidates who propose interdisciplinary projects bridging two or more of the following areas: algebraic and arithmetic geometry, random matrices and complex analysis, differential geometry, functional analysis and operator algebras, group theory, and Lie algebras. Postdocs will also have opportunities to guide PhD students and are expected to contribute to the research environment by organizing seminars and advanced courses. Teaching duties are limited. KU Leuven is committed to diversity and encourages applications from underrepresented groups. Applicants must have a PhD in mathematics (or be close to completion, with the degree expected before fall 2026), a strong research record in one of the specified areas, and fluency in English. The fellowship is for three years and includes a competitive salary, funding for conferences and research stays, health insurance, and social benefits for the postdoc and their family. The start date is flexible, preferably before October 2026. Applications must be submitted online, including a motivation letter, CV (with publication list, three references, and PhD defense date), and a three-year research plan. References will be contacted for letters if shortlisted. Interviews will be held in January 2026. For further information, contact Prof. Karel Dekimpe at [email protected].
