Nelson Liu

Hi! I recently graduated from the University of Washington, where I received degrees in computer science and linguistics. In Fall 2019, I will start a PhD in computer science at Stanford University.

I work on natural language processing, and I'm particularly interested in understanding and augmenting the generalizability and robustness of natural language processing systems.

Previously, I spent four amazing years as an undergraduate at 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 (especially those at the University of Washington) get started with research—feel free to email me!
