Spencer is a second year M.S. student in the Department of Computer Science at the University of Illinois at Urbana-Champaign. His research interests are in computational complexity, algorithms, and logic. He received his B.S. from Brown University in 2014, where he was a TA for 3 semesters, and was head TA for a brand new course on formal methods for software design. During a summer, he built an online block-based editor for Bootstrap, a curriculum for middle schoolers recently recognized by the White House. After graduating, he joined YouTube, working on the HTML5 video player used daily by millions worldwide. He was responsible for launching HTML5 live streaming, among other accomplishments. As a graduate student, he’s been investigating the expressive power of stochastic automata, and is currently attempting to characterize the complexity of a group of search problems related to the computation of equilibria in games and markets.
