Postdoc project "Quantum Markov Semigroups: from Geometry to Classification

Postdoc in operator algebras.

Vacancy is for a two-year postdoctoral position within the joint project "Quantum Markov Semigroups:
From Geometry to Classification", coordinated by Martijn Caspers (TU Delft) and Melchior Wirth (Universität Leipzig). The position will be fully based at TU Delft and primarily supervised by Martijn Caspers. Regular short research visits to Leipzig are an integral part of the project.

We are seeking candidates with a PhD in Mathematics who can successfully conduct research in one or more of the following areas:

• Von Neumann algebras
• Analysis of quantum information
• Quantum Markov semigroups
• Connections between operator algebras and geometric aspects of discrete groups or noncommutative spaces

During the postdoctoral appointment, there will be opportunities to pursue both independent and collaborative research. You will join our active Analysis Group at TU Delft, with established connections to researchers in quantum information physics.

We expect you to hold a PhD degree in Mathematics and have a proven track record in one of the directions: operator algebras with a focus on von Neumann algebras, operator spaces, quantum Markov semigroups, analytical aspects of quantum information theory.

We furthermore expect you to be fluent in English both in speaking and writing and able to communicate in an academic environment.

• Duration of contract is 1 year with prospect for another year.
• A job of 36-40 hours per week.
• Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.

• Plenty of opportunities for education, training and courses.
• Partially paid parental leave
• Attention for working healthy and energetically with the vitality program.

Are you interested in this vacancy? Please apply no later than January 14, 2026 via the application button and upload the following documents:
