I was a Dance major at the University of California, Irvine for the first two years of my undergraduate studies (Fall 2003 until Winter 2005), and an Information and Computer Sciences major for the second two years (Spring 2005 until graduation at the end of Spring 2007).
Why the change? In short, my mind is more suited to computer science than my body is to dance. I had been taking computer science courses since high school and had been tremendously interested in programming since the young age of 14. While a young teenager, I wrote several small programs in my spare time and built a great intuition for programming at an early age. This made the transition from a Dance to an ICS major much smoother and much less of a shock during my undergraduate studies.
Perhaps most importantly, during my junior year (winter quarter of 2006), Bill Tomlinson showed up in my classroom to recruit students for his research group, the Social Code Group. Research was a passion I never knew I had, so I got in touch with him to ask if he'd have me. Bill accepted me into the group and we went on to work on some projects, including FoG (a successor to The EcoRaft Project) and MDSE: Multi-Device Software Engineering (the topic of my undergraduate thesis).
