I’m a research scientist at Google Brain in Seattle. My research interests are centered around self-supervised methods for natural language processing.

Before joining Google, I completed my PhD at the University of Washington where I was advised my Luke Zettlemoyer and Dan Weld. When I am not doing Computer Science-y stuff, I like to hike, travel, and read.
