Postdoctoral Researcher in Mathematics or Computer Science: Lattice-Based Cryptography

We are looking for a post-doctoral researcher in the area of lattice-based cryptography. Possible research topics include:
  • Cryptanalysis of lattice problems
  • Side-channel analysis of implementations of lattice-based cryptography
  • Lattice-based cryptographic protocols
  • Construction of new candidate structures suitable for, e.g., the ring learning with errors (RLWE) problem and its variants.

Research experience in cryptography is essential. Additionally, background in algebraic number theory, probability theory, complexity theory and/or machine learning are useful. For a cryptographer, we expect that the candidate has published in IACR conferences, established theoretical computer science venues (STOC/FOCS/APPROX-RANDOM/SODA/PODC) or IT security venues (CCS/S&P/Usenix). The applicant is expected to hold a PhD degree in mathematics or computer science. A research level proficiency in English, both writing and speaking, is expected.

We offer advising related to both algebraic lattices (Camilla Hollanti) and cryptography (Chris Brzuska). Our group offers a diverse, international, and open research environment. We expect the candidate to significantly shape the research questions which we investigate together as well as to pursue their own research with their existing research network. Additionally, the candidate can benefit from our extensive academic and industrial networks.

Formally, the position will be supervised by Camilla Hollanti and be part of the Algebra, Number Theory, and Applications (ANTA) Group. ANTA is part of the Department of Mathematics and Systems Analysis which hosts several strong research groups, including Chris Brzuska Group. Chris Brzuska has a double appointment at the Department of Computer Science (, which is home to several strong research groups in machine learning and complex systems as well as theoretical computer science.

The tentative duration of the position is September 2022 — December 2023 (16 months), but a shorter duration or an earlier starting date is negotiable. There is an option to renew the contract subject to acquiring funding (either by the candidate or by the hosts). The initial salary is €3700 and the contract includes occupational health care.

Your application should include the following documents:
  • Statement of purpose (describe your motivation, mathematics and other relevant skills, scientific interests and career goals, and mention your preferred starting date).
  • CV.
  • University transcripts (with clear explanation on the grading scale).
  • PhD certificate (or estimated graduation date if not yet finished).
  • Names and contact details (positions, emails and phone numbers) of two references

For additional information on the position, please contact Camilla Hollanti or Chris Brzuska (both eMails: For submission related queries, contact Johanna Glader (
