I am a seventh-year assistant professor in the Colorado Computer Science Department. Previously, I was a postdoc and then professor in Maryland's Computational Linguistics and Information Processing lab. I was a graduate student at Princeton with David Blei. My research focuses on making machine learning more useful, more interpretable, and able to learn and interact from humans. This helps users sift through decades of documents; discover when individuals lie, reframe, or change the topic in a conversation; or to compete against humans in games that are based in natural language.
