I'm an MPhil student in Data Science and Analytics at HKUST(GZ) in Guangzhou, China. My supervisor is Prof. Nan Tang and Prof. Xuming Hu. I am also fortunate to work with Dr. Shuo Chen and Dr. Xuan Feng during my internship at Microsoft Research Asia. Before that, I got my Bachelor's degree at Huazhong University of Science and Technology(华中科技大学).

Research

My research explores the frontiers of Large Language Models (LLMs), with a focus on building robust Retrieval-Augmented Generation (RAG) pipelines and intelligent Agents that can act like human-experts. I am passionate about applying this work as "AI for X," creating systems that serve as expert assistants to accelerate discovery in science and industry.
