Jiaheng Liu
Currently, I am an Assistant Professor at Nanjing University (2025-Present), leading the NJU-LINK Lab.
Note that our lab usually has 2 PhD and 3 Master's positions available each year.
Meanwhile, I am one of the founding members of Multimodal Art Projection (M-A-P), which is an open-source research community on AIGC topics (e.g., text, audio, and vision modalities).
Previously, I was a Research Scientist (Alibaba Star Project) at Alibaba (2023-2025), focusing on Large Language Models (LLMs), including pretraining, long-context modeling, reasoning, and alignment.
I am actively looking for research interns and candidate students to work on LLM-related research topics. Please feel free to drop me an email to liujiaheng@nju.edu.cn if you are interested.

Moreover, I interned at SenseTime (working with Dr. Yichao Wu, Dr. Ding Liang), Baidu (working with Dr. Tan Yu), and Shanghai AI Lab (working with Dr. Tong He, Prof. Wanli Ouyang). I got my Ph.D. degree from Beihang University, advised by Prof. Ke Xu and Prof. Dong Xu. Earlier, I obtained my bachelor's degree from Beihang University.
I am currently working on Foundation Models, which is a promising direction to AGI.
