affiliations: Semi-retired, I still work on technical things but do not desire an employer or boss---or to be a boss. Mostly I'm working on building radically simpler and more secure systems. From time to time I advise startups like K2 Cyber Security, Stripe, and TerraTrue. I also have time to spend on hobbies like flying my Cessna 182 around the country.
After a transition handing the reigns to my successor and working on upspin, I retired from Google in March 2017 where I had been Vice President at Google, responsible for Security and Privacy Engineering. Obviously I'm biased, but I think Google Security Team is one of the finest groups anywhere. I'm in awe of the things they accomplish. Good thing, too, because we're stewards of data for billions of people and we have very skilled and persistent adversaries.
Before Google, I was technical lead on CloudControl, an internal venture building a security product for defending against unwanted network traffic. Before that, I was head of the Secure Networking Research Department in the Computing Sciences Research Center at Bell Laboratories in Murray Hill, NJ. I joined Bell Labs straight out of graduate school and was happily there through many company changes. Bell Labs is currently part of Alcatel-Lucent. I retired in April 2007.
