I teach and research computer security with a focus on applied crypto, security economics and human factors. I'm currently interested in verifiable lotteries, cryptocurrencies and encrypted communication tools. In the past I've worked on HTTPS, web authentication, side channels, software obfuscation, and privacy in social networks.

I'm co-author of a textbook on cryptocurrencies which you can read for free online.

I'm always interested to talk to students about research ideas. If you're a prospective PhD student or post-doc, or current NYU undergrad or master's student, get in touch to see if we can find a project together. Please include something you learned from my "about" page so I know haven't spammed every faculty web page you can find.
