My training is in cryptography, security, and privacy. At various points and places, I've studied combinatorics, number theory, elliptic curves, medical device security, and anticensorship systems, and have developed a fondness for probability and statistics.

Theory aside, I'm concerned with the design and implementation of systems that are protective of security and privacy. I daydream about the role of cryptography in society and social change.

A place for pictures and ideas to land, from comments on recent reading to the rough ideas informing my formal writing. And my travel blog, started when I travelled across North America towing my airstream. Often written with coffee at hand.
