I recently graduated from Stanford!
My research goal is to build explainable machine learning systems to help us solve problems efficiently using textual knowledge. I believe that AI systems should be able to explain their computational decisions in a human-understandable manner, so as to build trust in their application to real-world problems. To this end, I have been working on natural language processing (NLP) techniques that help us answer complex questions from textual knowledge through explainable multi-step reasoning, as well as models that reason pragmatically about the knowledge of their interlocutors for efficient communication in dialogues.
Outside of NLP research, I am broadly interested in presenting data in a more understandable manner, making technology appear less boring (to students, for example), and processing data with more efficient computation. I have also worked on speech recognition and computer vision previously.
When I procrastinate in my research life, I write code for Stanza, a natural language processing toolkit that’s available for a few dozen (human) languages, written in Python.
