concurrency, and blockchain
Cryptology and Data Security Group, University of Bern
Multiple Ph.D. positions are available in the Cryptology and Data
Security research group at the Institute of Computer Science,
University of Bern, led by Christian Cachin.
Our research addresses all aspects of security in distributed systems,
especially cryptographic protocols, consistency, consensus, and
cloud-computing security. We are particularly interested in
blockchains, distributed ledger technology, cryptocurrencies, and their
security and economics. Please explore crypto.unibe.ch to learn
more about our research topics. We are part of IC3: The Initiative
for Cryptocurrencies and Contracts (https://www.initc3.org/).
These positions concern smart contracts running on blockchains with a
cryptocurrency, blockchain consensus protocols, transactions, and
concurrent execution of programs. Candidates are expected to
investigate novel methods and protocols for scaling blockchains.
Candidates should have a strong background in computer science. They
should like conceptual, rigorous thinking for working theoretically, or
be interested in building innovative systems for working practically.
Demonstrated expertise in concurrent systems, distributed computing,
security, or blockchain technology is a plus. Applicants must hold a
master degree in computer science or a closely related research field
and ideally have already gained experience in the relevant research
areas.
The positions are available starting 1 March 2026 and run for up to
four years. The positions come with a competitive salary and are
governed by the [1] rules for doctoral studies and the [2] doctoral
agreement at the University of Bern. The University of Bern conducts
excellent research and lives up its vision that "Knowledge generates
value". The city of Bern lies in the center of Switzerland, it offers a
high quality of life and provides rich cultural and outdoor activities.
If you are interested, please apply by sending email with **one single
PDF file** and subject line set to **Application for Ph.D.** addressed
directly to Prof. Christian Cachin at **crypto.inf (at) unibe.ch.**
Applications received before November 15th will receive full
consideration, and the selection process runs until suitable candidates
have been found.
Your application should include:
* Cover letter, explaining your motivation.
* Curriculum vitae.
* Transcript of studies.
* Contact information for one or two references.
