I am a researcher working on artificial intelligence and machine learning, with particular application to the understanding of human communications. My work focuses on developing methods to help computers understand and extract information from natural language sources such as newspapers and websites. I am currently an Applied Scientist on Amazon's Product Graph team.
I hold a PhD in Computer Science & Engineering from the University of Washington, where I was advised by Hannaneh Hajishirzi and additionally supervised by Xin Luna Dong. Our work on the Ceres project was the subject of Luna's keynote address at the 2020 Conference on Information and Knowledge Management (CIKM).
I also hold a BA in English from Harvard University and an MA in Interdisciplinary Computer Science from Mills College. Prior to starting my PhD, I completed a stint with the Big Data Analytics & Machine Intelligence group at NASA Langley Research Center, taught at Peking University in Beijing, and did some time in the business world.
