Georgia Tech Professor John Bartholdi has passed away. He was my advisor, my mentor, and my friend. His passing leaves a terrible hole, but I am incredibly grateful for the impact he has had on me both professionally and personally. @GeorgiaTechISyE #orms @GeorgiaTechISyE On the professional side, he, Craig Tovey and I spent a fantastic few years writing papers that would become a foundation for the field of computational social choice. After sitting dormant (citation-wise) for fifteen years (from 1990-2005), the impact of those papers exploded.
