About Me

I’m a national security attorney based in San Francisco. I have extensive experience designing and overseeing compliance programs. I have unique abilities to apply my technical skills in creative ways and to communicate complex technological issues to people without engineering backgrounds. I’ve worked for the National Park Service in Yosemite, Earthjustice in Alaska, and a law firm in New York. During college and law school, I worked as a web developer and created an interactive system that diagrams relationships among terrorist organizations. In my spare time, I enjoy photography, hiking, sports, travel, and tinkering with computers.
