Jixuan (Lydia) Chen
Hi there!👋 I am a second-year Ph.D. student at UC San Diego, advised by
Prof. Lianhui Qin .
Prior to this, I received my B.E. in Software Engineering from Nanjing University with honors. I was
fortunate to work at XLANG
Lab (as part of the HKU
NLP
Group ) with Prof. Tao Yu on Computer Use Agents and
text-to-SQL Code Generation.
My research interests lie in ML and NLP. Nowadays, I am working on Multimodal
LLM reasoning and Embodied agents.
Feel free to reach out - let's see what we can create together!
