I am an assistant professor in computer science at UMass Amherst. Previously, I was a Young Investigator at AI2; before that, I completed my PhD at the University of Maryland, College Park, advised by Jordan Boyd-Graber and Hal Daumé III. My research interests lie broadly in natural language processing and machine learning. Much of my work uses deep learning to model language at the discourse level. Problems in this vein that I'm currently excited about include:

(1) generating long, coherent units of text
(2) answering questions about documents
(3) understanding narratives in fictional text
