👋 Hi! I am Hongxin Xiang. I graduated from College of Computer Scienceand Electronic Engineering, Hunan University with a Ph.D. degree, advised by Prof. Xiangxiang Zeng, in June 2025. From 2022.10 to 2025.03, I worked as a drug development scientist at Yuyao Biotechnology Co., Ltd, led by Prof. Mingyao Liu. My research has centered on the AI4Science, including bioinformatics, drug discovery, quantum machine learning, and graph- or geometry-based learning.

🔬 I also collaborate with Prof. Feixiong Cheng from the Cleveland Clinic, Li Zeng from Yuyao Biotech, Xin Jin from EIT, Jun Xia from Westlake University, and Wenjie Du from USTC, etc., closely. If you are seeking any form of academic cooperation, please feel free to email me at xianghx21@gmail.com.
