About me
Welcome! I’m a PhD student (2023-) at UC San Diego, working with Prof. Julian McAuley on the intersection of NLP and personalization. I’m also broadly interested in language technology for user-facing systems.
I did my undergraduate study at UC Irvine, where I worked on robustness and interpretability in NLP with Prof. Sameer Singh.
