Short bio: Joachim is a PhD candidate at Stanford advised by David Tse. His current research focus is the science and engineering of Internet-scale consensus (or, if you prefer more hype terms: the technical foundations of blockchains). Recent research projects include provable consensus security for next-generation Ethereum, and provable security and performance of proof-of-stake consensus under rate constraints (communication, processing, ...) 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.
