I am a 5th year PhD Candidate in the Department of Computer Science at the University of Colorado, Boulder advised by James H. Martin. My research interest lies in the fundamental understanding of actions and events in language and efficient Natural Language Processing. My most recent projects revolve around tractable methods for Event Coreference Resolution. I also interned twice at explosion.ai (makers of spaCy).

"Why didn't anyone do this before?!"
