News! We are looking for one or more post-doctoral fellows interested in MPC, secure distributed systems, and blockchain security and privacy. More details below.

Brief Bio

Prof. Aniket Kate is an assistant Professor in the computer science department at Purdue university. He is an applied cryptographer and a privacy researcher. His research builds on and expands applied cryptography, distributed computing, and data-driven analysis to solve security/privacy problems in decentralized environments. His current projects focuses on communication freedom and distributed ledgers (or blockchains). He is a recipient of the NSF CAREER Award for 2019.

Before joining Purdue in 2015, he was a junior faculty member at Saarland University, Germany. He completed his postdoctoral fellowship at Max Planck Institute for Software Systems (MPI-SWS), Germany. He has received his PhD from the University of Waterloo, Canada, and his masters from IIT-Bombay, India.

Opening for Post-Doctoral Researcher

I am looking for an outstanding post-doctoral researcher (or an extended visitor) working on topics related to applied cryptography and secure distributed systems.

Our research addresses all aspects of security and privacy of distributed systems, especially distributed cryptographic protocols, concurrency, and consensus. We are particularly interested in their applications to distributed ledgers (or blockchains) and cryptocurrencies.

The application must include a curriculum vitae, a short research statement, and names of 2 contacts that can provide reference about the applicant and her/his work. The candidate shall be able to demonstrate solid expertise in cryptography/distributed systems illustrated in form of publications at top crypto/security/systems venues such as CRYPTO, EUROCRYPT, ASIACRYPT, ACM CCS, IEEE S&P, USENIX Security, NDSS, SOSP/OSDI, NSDI, EuroSys etc.
