About this position

Doctoral student in the Foundations of Cryptography at Chalmers University of Technology in Gothenburg, Sweden.

The Crypto Team and Security Group at Chalmers invite applications for a doctoral student position supervised by Christoph Egger. The project sits within the Department of Computer Science and Engineering, a joint department of Chalmers and the University of Gothenburg, and is embedded in an internationally visible research environment with strong links across computing science, security, and trustworthy systems.

Possible research directions include fine-grained and bounded-space cryptography, realizations of idealized models, relationships between cryptographic notions, and related topics in foundational cryptography. The project may also include work at the intersection of cryptographic protocols and formal methods. Applicants are expected to be interested in the mathematical analysis of algorithms and cryptography, and the department encourages one or two extended research visits during the PhD.

The position is fully funded from the start. It is a fixed-term appointment for four years, with teaching or other duties of up to 20% of working time, which can extend the position to five years. The starting salary is 35,725 SEK per month (valid from May 1, 2026). Doctoral studies require physical presence for the entire study period.

Eligibility requirements include a Master’s degree in Mathematics, Computer Science, or a related field; for applicants educated outside Sweden, a 4-year Bachelor’s degree may be accepted. Candidates should have strong written and spoken English, mathematical maturity, and the ability to read and write proofs and formal definitions. Experience in cryptography, probability theory, complexity theory, or formal methods is advantageous. Swedish courses are available for interested students.

Applications must be submitted in English via the online system by August 14, 2026. Required documents include a CV, personal letter, a brief motivation statement, an explanation of the intended PhD focus and how it connects to prior experience, and bachelor’s and, if available, master’s thesis documents with transcripts. Incomplete applications and applications sent by email will not be considered.

Funding details

Full funding including tuition fees and living expenses is available for this position. The scholarship covers all educational costs and provides a monthly stipend.

How to apply

Please submit your application including a cover letter, CV, academic transcripts, and contact information for two references. Applications should be sent via the online portal before the deadline.
