Dr. Jeff Decker is managing director of the Technology Transition for Defense Program and co-instructor of Hacking for Defense at Stanford University. Before academia, Jeff served in the U.S. Army as a 2nd Ranger Battalion light infantry squad leader in Iraq and Afghanistan. After, he received his PhD in International Relations and went on to teach at Stanford. On this episode of the Defense Tech Underground, Dr. Decker discusses his experiences as a squad leader in the Army's elite Ranger Regiment in Iraq and Afghanistan, where he conducted more then 200 direct action raids. He tells of how he bet everything and moved across the country in the hopes of landing a teaching job with Hacking for Defense at Stanford. Finally, Jeff discusses the Hacking for Defense methodology - featured in his new book - for getting out of the building, knowing your users, and creating something your users will pull out of your hands.
