PhD @ PolyU · LLMs, model merging & alignment

Hello there! I’m Guodong Du, a PhD student at The Hong Kong Polytechnic University (PolyU). Before that, I was a research assistant at the Knowledge and Language Computing Lab @ Harbin Institute of Technology (Shenzhen), working with Prof. Jing Li. Earlier, I was a master’s student and research intern at the Learning and Vision Lab @ National University of Singapore, advised by Prof. Xinchao Wang and Jiashi Feng, and interned at Huawei Noah’s Ark Lab.

My research centers on large language models — model merging & knowledge fusion, post-training & alignment (RLHF / multi-objective), and training & inference efficiency (compression, pruning, quantization). More recently I also work on multimodal LLMs and embodied intelligence (Vision-Language-Action).
