Short bio: Joachim is a PhD candidate at Stanford advised by David Tse. His research interests include decentralized-systems security, distributed systems, applied cryptography, networking, and communications. Recent projects include Internet-scale consensus for heterogeneous user-bases, with applications to provable consensus-security for the Ethereum blockchain, and provable security and performance of consensus protocols under (communication, processing, ...) rate constraints and network-level attacks. While a Masters student at Technical University of Munich and a visiting student researcher at MIT, EPFL, and KAUST, he worked in information and coding theory. He has been supported by Protocol Labs PhD Fellowship, Ethereum Foundation, Stanford Graduate Fellowship, and German Academic Scholarship Foundation.
