About the job

A postdoc position is 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 .

Tasks

This position concerns smart contracts running on blockchains with a cryptocurrency, blockchain consensus protocols, transactions, and concurrent execution of programs. The candidate is expected to develop novel methods and protocols for scaling blockchains.

Requirements

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 Ph.D. in computer science (or obtain it before the position starts) and ideally have contributed to the relevant research areas.
