Han (Felix) Yan

Hi, I am Han (Felix) Yan (严涵), a fourth year undergraduate student studying at the The Chinese University of Hong Kong, Shenzhen. I was also an exchange student at the University of Notre Dame. I am fortunated to be advised by Prof. Jianwei Huang at the NCEL lab, Prof. Meng Jiang at the DM2 lab and Prof. Benyou Wang at the CUHKSZ Freedom AI lab.

My research interest lies in GenAI (e.g. MLLM/LLM/) Safety, AI Privacy, Trustworthy AI, CoT, Reinforcement Learning Reward Model and etc. Currently, I am exploring CoT and RL Reward Model Design.

Please feel free to drop me an Email for any form of communication or collaboration!

2025
PRISM Dual-Space Smoothness for Robust and Balanced LLM Unlearning
Han Yan*, Zheyuan Liu*, Meng Jiang
ICLR 2026.

We propose a unified framework that enforces dual-space smoothness in representation and parameter spaces to improve robustness and balance unlearning metrics.

Synthetic Power Network Topology Generation with Geographical Information Synthetic Power Network Topology Generation with Geographical Information
Yulin Song, Han Yan, Chenxi Sun, Jianwei Huang
Proceedings of ACM E-Energy 2025.

We propose an approach that diversifies grid representations and includes a rigorous evaluation process using multi-modal large language models (MLLMs) to ensure output consistency.

2024
SCEMS An LLM-Assisted Framework for Synthetic Power Network Graph Generation
Yulin Song, Han Yan, Chenxi Sun, Jianwei Huang
SCEMS 2024 (Best Oral Paper).

We propose a large language model-assisted workflow for small-scale synthetic power grid generation, verification, and visualization.
