Ph.D. Position in Post-Quantum Cryptographic Engineering, University of Tartu, Estonia

*Ph.D. Position in Post-Quantum Cryptographic Engineering*

The Cryptography Research Group at the Institute of Computer Science at the
University of Tartu invites applications for a Ph.D. position in applied
post-quantum cryptography, with a focus on the efficient and secure
implementation of lattice-based cryptographic schemes. The selected
candidate will design, implement, and analyze practical lattice-based
cryptographic primitives that remain secure against quantum-capable
adversaries. The research will emphasize high-performance implementations,
scalability for real-world systems, and strong protection against
implementation-level threats such as side-channel attacks. This position
offers the opportunity to work on cutting-edge problems at the intersection
of cryptographic theory and practical deployment, contributing to the
design and analysis of cryptographic protocols that provide strong,
provable security guarantees while achieving efficiency and scalability in
modern computing environments.

Candidates with experience in lattice-based cryptography or related areas
of computer science and mathematics are especially encouraged to apply.
Applicants should hold (or expect to obtain by spring) an MSc degree or
equivalent with a research thesis and have a solid background in
mathematics or theoretical computer science, including prior exposure to
cryptography. Strong written and spoken English skills are required.
Programming experience particularly in Python/SageMath/Magma and/or C/C++
and/or Java and/or Verilog HDL is highly desirable.

The PhD position begins on *September 1, 2026*, and has a duration of four
years. The successful applicant will work as a *junior research fellow*
under the supervision of Sedat Akleylek, with potential collaboration from
other researchers in the group.

*About University of Tartu*

The University of Tartu is Estonia’s leading research university and a
recognized center for computer science and cryptography. The department is
located in the modern Delta Centre in central Tartu and hosts an
international community of faculty and graduate students working in areas
such as cryptography, coding theory, machine learning, and information
systems.

*About Estonia*

Estonia is often described as a leading *“digital nation”*, known for its
early adoption of nationwide digital services and home to companies like
Wise and Bolt. Tartu is a compact and vibrant university town with a lively
student community, short commuting times, and easy access to nature.

*About Salary*

PhD students receive a net monthly stipend of about €1900, while the cost
of living in Tartu remains relatively affordable. For instance, renting a
modern one-bedroom apartment in the city center usually costs below €600
per month. In addition to the salary, the position provides benefits such
as funding for research travel, social events, and language courses.

Other PhD and postdoc positions in the area of lattice-based cryptography
and zero-knowledge are available in our group's website

Interested candidates should send their applications (including CV,
B.Sc./M.Sc. thesis, academic transcripts and motivation letter with a brief
statement of research interests) to Sedat Akleylek, [email protected]
with the subject "Fall 2026 Ph.D. Application – Applicant’s Name"


The application deadline is *April 16, 2026*.
