I work on blockchain cryptography, computer and web security, privacy of data processing.
I am now on a sailing expedition with my family (since summer 2024).
I was a Research Partner at a16z crypto 2022-2024.
I received my PhD in Computer Science from Stanford University advised by Prof. Dan Boneh. I then worked as a Research Scientist on the Diem blockchain project at Meta before joining a16z.
