Dear colleagues, I am pleased to share the following call for applications: __________ *PhD or Postdoctoral Position in Probability Theory* *Ruhr University Bochum – Faculty of Mathematics* *Application deadline: June 27, 2026* The Faculty of Mathematics at Ruhr University Bochum invites applications for a *PhD* or *Postdoctoral* position in *Probability Theory*, with a flexible start date (no later than January 2026). The position is part of the research group of *Prof. Christoph Thäle*, which focuses on *stochastic geometry* and *geometric probability*. The group's research centers on the asymptotic behavior of random spatial structures – ranging from discrete to high-dimensional models – using tools from probability theory and geometric analysis. We are looking for a highly motivated candidate conducting independent research in a modern area of probability theory, ideally with a focus on stochastic geometry. Applicants should hold an excellent *Master’s degree* (for the PhD position) or *PhD* (for the PostDoc position) in mathematics, preferably in one of the following areas: - Probability theory - Geometry - Combinatorics *Position details:* - *PhD position*: 75% TV-L E13 (German public sector pay scale) - *PostDoc position*: 100% TV-L E13 *Application process:* Please submit your application *electronically* as a single PDF file, including: - a cover letter - a curriculum vitae (CV) - academic transcripts Send your application to: tanja.schiffmann@rub.de. For further information or inquiries, please contact *Christoph Thäle* ( https://sites.google.com/view/christophthaele/start). We look forward to receiving your application by *June 27, 2026*. __________ Best wishes, -- Nicola Turchi Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca
