Do you hold a Master’s degree and dream of pursuing a fully funded PhD in the Leiden, Netherlands? Great news! Leiden University now accepting online applications for fully funded PhD positions across a wide range of disciplines. Passionate and qualified candidates are encouraged to apply through the respective university’s official application portals and take the next big step in their research journey.”
1. Funded PhD Vacancy in Formal Methods for Safe AI
Position Description:
The PhD student will be embedded in the Theory cluster at the Leiden Institute of Advanced Computer Science, supervised by Dr. Emily Yu and Prof. Marcello Bonsangue at the Veritas lab. The successful candidate will conduct original and novel research developing verification, synthesis, and machine learning methods that ensure that digital, physical, probabilistic systems interacting with deep learning and neural network are formally guaranteed to be safe, publish and present scientific articles in top formal methods, AI/ML venues, contribute to educational activities as a (head) teaching assistant and finally write a PhD thesis detailing the outcome of the research activities.
Deadline to Apply: 21 January 2026
2. Funded PhD Vacancy in Statistics (survival analysis)
Position Description:
The Mathematical Institute of Leiden University invites applications for a PhD position in Statistics (survival analysis). This 4-year position is part of a research project on the development of new statistical methods for the dynamic prediction of time-to-event (survival) outcomes in complex longitudinal studies, led by dr. Mirko Signorelli and funded by the Dutch Research Council (NWO).
Deadline to Apply: 20 March 2026

3. Funded PhD Vacancy in Ion transport and synthesis of two-dimensional nanopores and nanoporous membranes
Position Description:
Current separation technology is crucial for many aspects of human life and accounts for ~15% of the world’s energy consumption. Additionally, in the development of next-generation power solutions based on fuel cells and ion batteries, the membrane is an essential component that directly determines device efficiency. While the particle flow through separation columns is directional at the atomistic scale, undirected Brownian motion dominates in state-of-the-art membranes.
Deadline to Apply: 5 January 2026
4. Funded PhD Vacancy in moduli of curves and abelian varieties
Position Description:
Applications are invited for a 4-year PhD position at the Mathematical Institute of the University of Leiden, as part of the ERC project Enumerative and Arithmetic Geometry of Logarithmic Curves. Moduli spaces of curves and abelian varieties play a central role in algebraic and arithmetic geometry, and can be studied from a variety of perspectives (modular curves, Shimura varieties, moduli spaces of flat structures, …). This project brings together a number of these approaches with applications to problems in enumerative geometry (specifically log Gromov-Witten theory; counting curves with tangency conditions) and in arithmetic geometry (understanding rational points on abelian surfaces).

5. Funded PhD Vacancy in Societies and Guilds in the Language Industry
Position Description:
The LangPro project examines the notion of the language sector in early modern North-West Europe: that part of early modern societies and economies which relied primarily on language skills. The early modern period saw a swift increase in occupational opportunities for men and women who possessed language skills such as reading, writing, and text editing in one or more languages.
Deadline to Apply: 15 February 2026
6. Funded PhD Vacancy in LangPro Women in the Early Modern Language Sector
Position Description:
The PhD candidate will conduct a collective analysis of a selection of early modern female language professionals from England, the Low Countries, France, and the German lands to explore to what extent women could benefit from employment in the language industry. Although women (with only a few exceptions) did not have access to academic education, language skills offered them a way to pursue intellectual professions, such as translator or language teacher.
Deadline to Apply: 15 February 2026
7. Funded PhD Vacancy in New K-theoretic invariants in quantum theory
Position Description:
The Mathematical Institute is looking for a PhD candidate to join the project, under the supervision of Francesca Arici, Bram Mesland and Irene Aguilera (UvA). Applications are invited for a 4-year PhD position at the Mathematical Institute of the University of Leiden, as part of the project New K-theoretic invariants in quantum theory within the national consortium.

8. Funded PhD Vacancy in Efficient AI for traffic management and decision support systems
Position Description:
The project aims to bridge the gap between recent advances in AI and machine learning, in particular, multimodal and instruction-tuned foundation models, and the complex operational challenges faced by traffic operators, municipalities, and mobility service providers. This includes the integration of symbolic reasoning, predictive analytics, and reinforcement learning within the context of intelligent traffic control systems.
Deadline to Apply: 18 December 2025
9. Funded PhD Vacancy in Animate matter
Position Description:
The aim of this project is to unravel the principles underlying the emergence of life by creating a new class of materials that we call animate materials – materials that possess life-like abilities such as motion, shape-morphing, and intelligent behaviour. This cutting-edge project will identify the general design principles to achieve these traits and develop and study experimental realization at the macroscopic and microscopic length scale.
