Postdoctoral researcher in matroid theory for post-quantum cryptography (m/w/d)

70 % (limited by 01.02.2026 until 31.01.2027)

Your tasks

We are seeking a highly motivated postdoctoral researcher to join our team in exploring the intersection of matroid theory and post-quantum cryptography. This position is part of a larger effort to develop novel cryptographic constructions based on combinatorial and algebraic structures beyond lattices.
The successful candidate will investigate how matroids-and related combinatorial structures-can be used to design cryptographic primitives that are secure against quantum adversaries.
 
The Position Involves:
  • Conducting independent and collaborative research in matroid theory and its applications to post-quantum cryptography, including publications in leading journals and conferences
  • Developing new theoretical frameworks and exploring connections to cryptographic hardness assumptions
  • Collaborating with PhD students and contributing to joint research projects
  • Participating in group meetings, seminars, and interdisciplinary discussions
  • Providing light teaching support, such as mentoring, occasional guest lectures, or assisting with graduate-level courses

Your profile

  • PhD in mathematics or theoretical computer science
  • Strong background in matroid theory, algebraic combinatorics, and discrete mathematics
  • Interest or experience in cryptography, especially post-quantum cryptographic models
  • Proven research ability and a strong publication record (relative to career stage)
  • Excellent written and oral communication skills in English
  • Ability to work both independently and as part of a collaborative team
The applicant will join the research group on coding theory and cryptography in the Institute of Computer Science (ICS-HSG) at the University of St.Gallen. The ICS-HSG is a research institute specialized in computer science and dedicated to scientific excellence to foster economic growth and societal well-being. Our fields of expertise range from artificial intelligence, cyber security, data science, communication systems, human-computer interaction, programming languages, and software engineering.

What We Offer:
  • A dynamic and collaborative research environment
  • Funding for travel to conferences and research visits
  • Opportunities to supervise students and co-author papers
