Alex Biryukov

The University of Luxembourg is seeking a postdoctoral researcher for the CryptoLux team, led by Professor Alex Biryukov, within the Interdisciplinary Centre for Security, Reliability and Trust (SnT). The successful candidate will contribute to the 'Advanced Cryptography for Finance and Privacy (CryptoFin)' project, funded by the Fonds National de la Recherche (FNR) through the CORE program. The research focuses on advanced cryptography applications in finance and privacy, including areas such as applied and symmetric cryptography, cryptofinance, cryptoeconomics, blockchains, and online anonymity. The postdoc will conduct, publish, and present research results at conferences, provide guidance to two PhD students, and help attract funding in collaboration with academic and industrial partners. Applicants should have a Ph.D. in Computer Science, Applied Mathematics, or a related field, with a strong record in applied cryptography or information security (including at least one publication in a top-tier conference). Strong mathematical and algorithmic skills, programming proficiency, and fluency in English are required. Experience in economics or finance is a plus. The position offers a fixed-term contract for 18 months, with a yearly gross salary of EUR 83,099. The University of Luxembourg provides a modern, international, and inclusive research environment, with high-quality equipment and strong ties to industry and European institutions. Applications must be submitted online, including a cover letter, CV, details of open-source contributions or competitions, and contact information for three referees. Early applications are encouraged as review is ongoing. The university values diversity and encourages applications from all backgrounds.

Postdoctoral Researcher in Cryptography and Privacy at the University of Luxembourg The Faculty of Science, Technology and Medicine (FSTM) at the University of Luxembourg is recruiting a postdoctoral researcher to join the CryptoLux Group led by Prof. Alex Biryukov . The group’s research spans symmetric cryptography, cryptography for blockchain and FinTech, and privacy applications, with particular attention to lightweight and ultra-lightweight cryptography, algebraic and arithmetization-friendly cryptography for zero-knowledge and MPC applications, privacy-enhancing technologies, and post-quantum cryptography. The successful candidate will lead high-impact research in cryptography and privacy, contribute teaching at bachelor, master, and PhD levels (up to 90 hours per year), support the daily supervision of PhD and MSc students, and help write research funding proposals. The postdoctoral fellow will report directly to the group head, Prof. Dr. Alex Biryukov. Applicants should hold a PhD in Computer Science or a related area such as applied mathematics. A strong publication record is expected, especially publications in A* venues in cryptography or information security. Excellent English proficiency at C1 level is required. The position is based at the Belval Campus in Esch-sur-Alzette, Luxembourg, within a modern, multilingual, and international university environment. The appointment is a fixed-term 24-month contract with a possible extension up to 5 years in total. The role is full-time (40 hours per week). No application deadline is stated; applications are processed upon receipt, and early application is encouraged. To apply, candidates must submit a CV with full bibliography, a cover letter explaining motivation and fit with the research topic/project, PhD diploma or expected defense information, degree certificates and transcripts, the names and contact details of up to three referees, and a publication list including open-access links where available. Applications must be submitted online via the HR system; email applications will not be considered.
