Leiden University's Mathematical Institute invites applications for a 3-year postdoctoral position in the field of moduli of curves and abelian varieties, as part of the ERC project 'Enumerative and Arithmetic Geometry of Logarithmic Curves' led by Prof.dr. David Holmes. The project focuses on two main research directions: developing cohomological field theory (CohFT) structures for logarithmic Gromov-Witten invariants, and advancing the understanding of the geometry of moduli spaces of genus 2 curves and abelian surfaces, with applications to rational torsion points on abelian surfaces. A key aspect involves studying differential forms on moduli spaces with level structure.
The position is open to candidates with expertise in any related area, including log geometry, modular and automorphic forms, moduli spaces, Gromov-Witten theory, classical modular curves, and integrable systems. The successful candidate will join an active and expanding group in enumerative and logarithmic geometry, within a larger research community specializing in algebra, geometry, and number theory. The Mathematical Institute offers a vibrant academic environment with regular reading groups and participation in national and international seminars.
The Mathematical Institute is part of the Faculty of Science and is committed to advancing mathematical knowledge and promoting mathematical literacy. Research themes include Algebra, Geometry and Number Theory, Analysis and Dynamical Systems, Probability, Operations Research and Dynamics, and Statistics, with extensive collaboration across these areas. The institute values inclusivity, diversity, and personal development, providing a supportive and intellectually stimulating atmosphere.
The postdoctoral appointment is full-time for three years (initially one year, extendable to three after a positive evaluation). The position offers a competitive salary (€3546–€5538 gross per month), holiday allowance (8%), end-of-year bonus (8.3%), pension scheme, full reimbursement of public transport commuting costs, flexible working hours, generous leave options, home-working allowance, and a university-provided laptop. The university is located in the historic city of Leiden, close to the city centre and The Hague.
Applicants must hold a PhD in mathematics and demonstrate a strong publication record. To apply, submit a CV (including publications), a research statement outlining past and future work, a motivation letter explaining your fit for the project, and contact details for three referees. The application deadline is 07 December 2025. For enquiries, contact Prof.dr. David Holmes at holmesdst@math.leidenuniv.nl.
