I am motivated by revolutionizing how society trades and interacts. Bitcoin and the security properties of its blockchain provide technical means to catalyze societal evolution. My research therefore focuses on the security, privacy and performance of blockchain technology. Because this technology is still in its infancy, I largely focus on understanding and quantifying the tension points and tradeoffs in terms of security, privacy and performance, with the goal to build a mainstream, scalable, open, and decentralized blockchain. Part of my research is e.g., the design of novel consensus mechanisms, connecting the real world with blockchain, and the development of practical and competitive blockchain applications. My research is inherently multidisciplinary and I frequently collaborate with colleagues worldwide in various fields (e.g., machine learning).
