About me

My name is Steven Goldfeder, and I am a fourth year PhD student in the Department of Computer Science at Princeton University. I’m a member of the Security & Privacy Research Group, a CITP Graduate Student Fellow, and a National Science Foundation Graduate Research Fellow. My advisor is Professor Arvind Narayanan.

My research interests include cryptography, security, and privacy. I am interested in decentralized digital currencies, and my current work involves increasing the security of Bitcoin wallets.

I can be reached at stevenag@cs.princeton.edu.
