Curriculum Vitae

Dave Levin


I work at the intersection of networking, distributed systems, security, and economics. I am currently working on moving towards a more secure PKI. My vision is of an Internet where users feel motivated and safe to help one another achieve better performance and reliability. I have been fortunate to work with many wonderful collaborators.

If you are a current or prospective student and interested in working together, feel free to drop me a line. You should also consider attending Syschat.
