Rico Angell

I am a Ph.D. candidate in computer science at University of Massachusetts Amherst working with Andrew McCallum on machine learning and natural language processing. My research interests include machine learning, optimization, and human-centered artificial intelligence. I am generously supported by the NSF Graduate Research Fellowship. My CV can be found here.

I completed my undergraduate degree at University of Michigan in Ann Arbor in computer science and engineering with a minor in math. I worked with Andrew DeOrio applying machine learning to hardware verification and Grant Schoenebeck on a heuristic for the influence maximization problem.
