I work at the intersection of networking, security, systems, and economics. I am passionate about understanding when and why security breaks down, and in building an Internet where users are safe and motivated to help one another achieve better performance and reliability. I am currently working on making the PKI more secure. On this, and other projects, I have been fortunate to work with many wonderful collaborators.

I am recruiting motivated PhD students; Drop me a line if you're interested


September 22, 2016 The next Build-it, Break-it, Fix-it secure programming competition starts tonight. Sign up and stay tuned for results.
