Theoretical Computer Science & Discrete Mathematics
How can we put the theory of algorithms onto a firm theoretical framework? What are properties of particular networks, graphs, hypergraphs, permutations or Latin squares under particular conditions? These are questions that are the core of the research of the Theoretical Computer Science and Discrete Mathematics group at Heidelberg University.
Open PhD and postdoc positions
Postdoc: 2-year position (extension possible)
PhD student: 3-year position
Starting date: Around September/October 2026 (negotiable)
Applications be directly sent to Felix Joos (joos@uni-heidelberg.de). For informal inquires, please get in touch with him.
Postdoc applicants should have a strong background in combinatorics. PhD applicants should have a degree in Mathematics or related. Please include in your application a cover letter, a CV, your master thesis (for the PhD position) and names of two to three people who are willing to write a letter of recommendation for you.
DEADLINE: all applications submitted until 12th January receive full consideration. The position remains open until filled.

The Theoretical Computer Science and Discrete Mathematics group at Heidelberg University was founded in 2020 when Professor Felix Joos joined Heidelberg University. The research group is part of the Institute of Computer Science and also supported by a Emmy Noether grant by the DFG, the cluster of excellence STRUCTURES, the Alexander von Humboldt foundation and the Studienstiftung des deutschen Volkes.
Since its foundation, the research group has grown significantly to one of the largest research groups in its field in Germany.
