Hi, I’m Vivian (Yiwei) Chen, an incoming Ph.D. student in Computer Science at the University of California, San Diego. I am fortunate enough to be jointly advised by Prof. Taylor Berg-Kirkpatrick and Prof. Rose Yu.
Research
My research interests include natural language processing, machine learning, and AI for science. I’m interested in data-efficient modeling, complex reasoning, pragmatics, and low-resource languages. I am also interested in multi-modal foundation models that integrate structured and textual data to advance scientific understanding.
In the past, I've worked with Prof. Kilian Weinberger on diffusion-guided language modeling (Findings, ACL 2024), with Prof. Yoav Artzi on retrospective learning from human feedback in interactions (ACL 2025 Oral), and with Prof. Tanya Goyal on unfactual outputs in large language models.
News
- 06/2025: Our paper Retrospective Learning from Interactions has been selected for an oral presentation at ACL 2025.
- 05/2025: I graduated from Cornell with a B.A. in Computer Science, Math, and Linguistics.

Miscellaneous
I'm a huge musical theatre fan. I worked for Tony Awards · China as a subtitle translator in 2024.
I like singing, reading, and watching movies. I quite enjoy learning languages, and I'm currently learning Japanese.
For sports, I like skiing and figure skating, and I play table tennis. I will definitely try surfing in San Diego!
I also do a bit of seal cutting in my spare time.
