About Me
I earned my Ph.D. (2021-2025) from the University of Liverpool, under the supervision of Professor Xiaowei Huang and Professor Xinping Yi. My current research focus on the following topics:
- Efficient AI (e.g., Hardware-Aligned Linear/Quasilinear Scalable Transformers)
- (Non-Euclidean) Geometric Deep Learning (e.g., Hyperbolic Graph Embedding)
- Human-AI Preference Alignment (e.g., RLHF, Red-teaming and Defence).
Before Liverpool, I received my dual bachelor’s degree (2017-2021) in Computer Science from both Australian National University and Shandong University.
