PhD in Computer Science, University of Waterloo. My thesis was sustainable-transportation focused.
I like helping out on various SE sites, most notably "StackOverflow" and "English Language and Usage". I recently (after finally submitting my thesis) started visiting "Academia". Lately I've been learning a lot from "CrossValidated" though I haven't been able to contribute to this yet.
