Rory Lewis is assistant professor of computer science at the University of Colorado at Colorado Springs. He is often mistaken for a hippie, wearing Dead-head shirts and walking aimlessly around the campus. He is often described as the guy in the office where students are always lined up outside. He is often heralded as the dude that will explain your math and computer code, even when he first checks and sees you ve done 800 tweets and 2,700 Facebook comments while you should have been in class! He is described by his adult daughters as a dad that was once a successful microprocessor litigation lawyer in Palo Alto, but couldn t resist his dorkiness and went back to school to become a doctor of geekdom!
