I am an Applied Scientist at Amazon Web Services. I recently completed my PhD at the Center for Language and Speech Processing at Johns Hopkins University, where I research natural language processing and artificial intelligence. I was advised by Benjamin Van Durme and supported by an NSF Graduate Research Fellowship.

I have interned with the Aristo reasoning team at The Allen Institute for Artificial Intelligence under Peter Clark. I also interned with Microsoft Semantic Machines under Harsh Jhamtani and with the Deep Learning & Language group at Microsoft Research under Marc-Alexandre Cote and Eric Yuan.

As an undergraduate at Brown University, I worked with Ugur Cetintemel and Carsten Binnig in the Database Group, where we built of the first neural approaches to parsing natural language into SQL.

My research interests include:
