I am a research scientist at ASAPP . Previously I received my PhD in Computer Science at Umass Amherst , working with Professor Andrew McCallum. My thesis topic is to represent graphs in a compact, geometric-based embedding space. I am broadly interested in natural language processing and machine learning.
During my research career, 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).
