About
I am advised by
Jordan Boyd-Graber at the University of Maryland, while also working closely with
Hal Daumé III,
He He,
Danqi Chen,
and
Sherry Wu.
In summer 2022, I did a research internship at Microsoft hosted by
Zhe Gan. Before that, I got into NLP research by working with
Min-Yen Kan and
Zhiyuan Liu.
Nowadays, I'm fascinated by
Human-Muppet Interaction.
And I'm particularly concerned about the following questions:
How can humans verify what Muppets said, especially in tasks where humans lack the domain expertise?
How can we enable human-Muppet collaboration to complete tasks that humans or Muppets cannot solve alone?
What is the long-term impact of humans relying on Muppets?
How can we measure and improve the safety of Muppets?
In pursuing these research questions, I tend to move away from existing benchmarks and put human needs at the
center of my research.
I also aim to craft an interdisciplinary research agenda that connects insights from HCI, NLP, ML, Psychology, and Linguistics.
Back in the old days, I also worked on Question Answering, Tokenization, and Prompting.
