Hi! I'm a second-year PhD student in computer science at Stanford University, where I work in the Natural Language Processing Group. My advisor is Percy Liang.

My research focuses on understanding and augmenting the generalizability and robustness of natural language processing systems. In general, I am interested in bridging the gap between solving individual NLP benchmarks and solving broader NLP tasks. My research is graciously supported by a NSF Graduate Research Fellowship.

Previously, I received undergraduate degrees in computer science and linguistics from the University of Washington, where I worked with Noah A. Smith. I've also spent time at the Allen Institute for Artificial Intelligence (AI2) (working with Matt Gardner), and the USC Information Sciences Institute (working with Kevin Knight and Jonathan May).

Thanks to the support of my research mentors, I was fortunate to begin working on research early in my undergraduate career. I’m happy to help ambitious undergraduate students interested in natural language processing or machine learning get started with research—please feel free to email me!
