PhD Position in Algebraic Topology

The Department of Mathematics of Vrije Universiteit Amsterdam welcomes applications for a 4-year PhD position in Algebraic Topology. The PhD student will work on topics in Topology such as manifold invariants, exploring links to Homotopy Theory and Mathematical Physics, under the supervision of Renee Hoekzema. Furthermore there is the possibility to work on applications of Topology in the Sciences.

Symmetry on the interface of topology and higher algebra
The position is part of the NWO ENW-XL project Symmetry on the interface of topology and higher algebra (https://www.math.ru.nl/symmetry/), based at Radboud University Nijmegen, Utrecht University, and Vrije Universiteit Amsterdam. This community meets frequently for shared events.

Topology and its applications at the VU:
Topology research at VU Amsterdam is part of the Center for Topology and its Applications (CTA^2 https://www.cta2.nl/) at the Department of Mathematics. We are an inclusive, interdisciplinary group, and diversity and internationalism is at the heart of our research principles, as well as our teaching practice.

The preferred starting date is 1 September 2026 (flexible).

Applications from all groups currently under-represented in academic posts are especially encouraged. We particularly welcome applications from women and people with an ethnic minority background.
