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. And prior to that 2018-2022 I was a Research Scientist at Meta working on the Diem project.
I received my PhD in 2017 in Computer Science from Stanford University advised by Prof. Dan Boneh.
