Jixuan Chen

Hi there! I am a 4-th year undergraduate student at Nanjing University, majoring in Software Engineering. Currently I'm working as a Research Assistant at XLANG Lab (as part of the HKU NLP Group) with Prof. Tao Yu. Before that, I was honoured to work with Prof. Shujian Huang at Nanjing University.

My research interests lie in ML and NLP. Nowadays, I am working on Computer Use Multimodal LLM agents and Code Generation.

Here is the problem I am thinking about: How to design smarter GUI agents with reinforcement learning (RL) and large language models (LLM)?

I am looking for a Ph.D. position starting in 2025 Fall. Please feel free to reach out!
