We are seeking a PhD student to carry out cutting-edge research in theoretical computer science, with an expected focus on cryptography.

Project Background

Current public-key cryptography is vulnerable to quantum attacks.
Code-based cryptography offers plausible security against quantum attacks and enables efficient implementations of advanced cryptography (secure multiparty computation, interactive proofs).
Open research challenges include:
- Lack of satisfactory theory of security reductions
- Insufficient cryptanalysis of recent proposals

The PhD project aims to strengthen the foundations of code-based cryptography and will benefit from collaboration with experts from CWI cryptology group and QuSoft.

Responsibilities

As a PhD candidate, you are expected to:

Carry out original research in theoretical computer science
Apply strong analytical and mathematical skills
Seek collaborators and identify research topics worthy of study
Participate in educational activities (assisting in courses, guiding student theses)
Publish in peer-reviewed journals and present at international conferences
Participate in committees and departmental administrative tasks

Candidate Profile

MSc in computer science, mathematics, or a related field
Strong scientific interest in the theory of computing
Strong academic performance in computer science, mathematics, or related courses
Demonstrated ability to conduct cutting-edge research
Willingness to work collaboratively with other researchers
Professional command of English and good presentation skills

Employment Details

Contract: Temporary, 38 hours per week, duration 4 years
- Initial 18 months, extendable to 4 years after satisfactory evaluation
- Preferred start: as soon as possible
Salary: €3,059 – €3,881 gross per month (38-hour week), excluding 8% holiday allowance and 8.3% year-end allowance
Benefits: UFO profile PhD Candidate, 30% ruling may apply for non-Dutch applicants, Collective Labour Agreement of Universities of the Netherlands

Educational plan includes course attendance, international meetings, and assistance in undergraduate and MSc teaching.

Work Environment

Faculty of Science: ~8,000 students, 1,800 staff
Informatics Institute (IvI): research in AI, Computational Science, Systems and Network Engineering
Theory of Computer Science (TCS) group: research on theoretical foundations and computational limits
Access to active theoretical computer science research community at Amsterdam, CWI, and QuSoft

Application Procedure

Apply online by May 1, 2026. Include the following:

Detailed CV (months and years of education/work experience)
Motivation letter (max. 1 page)
List of publications
Research project report (e.g., Master thesis)
