Amherst, MA 01002

I am a PhD student in Computer Science at Umass Amherst , working with Professor Andrew McCallum. My current research focus is to represent graphs in a compact, geometric-based embedding space. I am also broadly interested in information extraction, NLP, and machine learning.

During my research carear, I have had the great pleasure collaborating with Michael Boratko (UMass), Lorraine Li (UMass), Sunil Mohan (CZI), Subhabrata Mukherjee (now at Microsoft), Luna Dong (Amazon, now at Meta), Sujian Li (Peking University), and Dong Wang (Tsinghua University).
