I direct the Broadening Linguistic Technologies Lab at Brandeis University, where I am affiliated with the Michtom School of Computer Science and the Computational Linguistics Program. The overarching goal of my research is to broaden the depth and breadth of human language technology, with a focus on understudied problems in natural language processing (NLP).

My current work focuses on eliminating the barriers to useful language technology for every living written language, especially lower-resourced and minoritized languages. I have previously worked on human-robot interaction and the representation of language in the mind, including language acquisition, processing, and change.

I did my graduate work in Computer Science at The University of Pennsylvania (Ph.D. 2013), advised by Mitch Marcus and Charles Yang. I then completed a post-doctoral fellowship at The Children’s Hospital of Philadelphia exploring clinical applications of statistical models of language processing. I was a researcher at BBN Technologies and USC Information Sciences Institute. In summer 2019, I joined the computational linguistics faculty at Brandeis University.
