I am a Research Scientist at the Ethereum Foundation, working on the long-term evolution of Ethereum's consensus protocol as part of the Protocol Consensus team. My current focus is on faster finality — the formal question of when a distributed network can irreversibly confirm a transaction — and on designing protocols that achieve this efficiently, securely, and under realistic network assumptions.
More broadly, my research spans consensus protocols, Byzantine fault tolerance, and the security foundations of distributed systems. I hold a PhD in Computer Science from the University of Bern, where I worked under Prof. Christian Cachin on the theory of asymmetric trust — a formal model allowing different participants in a network to hold different trust assumptions about each other.
My academic background is in Mathematics, studied at Università Cattolica del Sacro Cuore, with a focus on abstract algebra and cryptography.
