I teach and do research spanning cryptography, security protocol design, security economics, and human factors in security. I'm interested in making systems more trustworthy and transparent, particularly encrypted communication tools, cryptocurrencies, and HTTPS and PKI on the web. My past research has spanned passwords and authentication, side-channel cryptanalysis, protocol verification, software obfuscation, and privacy in social networks. I'm co-author of a textbook on cryptocurrencies which you can read for free online.
