Dr. Long CHEN (Chinese: 陈隆) is an assistant professor at the Department of Computer Science and Engineering (CSE), Hong Kong University of Science and Technology (HKUST) starting from 2023. He is leading the research group: LONG Group. Before joining HKUST, he was a postdoctoral research scientist at the DVMM Lab, Columbia University working with Prof. Shih-Fu Chang (2021 - 2023). He obtained his Ph.D. degree in Computer Science from Zhejiang University and his Ph.D. advisor is Prof. Jun Xiao (2015 - 2020). During his Ph.D. study period, he also worked closely with Prof. Hanwang Zhang from Nanyang Technological University (NTU) and Prof. Tat-Seng Chua from National University of Singapore (NUS). He obtained his B.Eng. degree in Electronic Information Engineering from Dalian University of Technology (2011 - 2015). He was a senior research scientist at Tencent AI Lab (2020 - 2021).

Research Group: LONG Group @ HKUST CSE

1. Based on the current funding situation, we have only extremely limited postdocs, research assistants, and visiting students openings. (Please also highlight if you have other funding sources or supports).
2. As for Ph.D. and M.Phil. positions, we always have the openings all year around.
3. To further increase the diversity, Ph.D./M.Phil applicants from overseas countries and HK are strongly recommended.

Research Interest

His primary research interests are Computer Vision, Machine Learning, and Multimedia. Specifically, he aims to build an efficient vision system that can understand complex visual scenes as humans. By “human-like”, we mean that the vision systems should be equipped with three types of abilities:

1) Explainable: The model should rely on (right) explicit evidences when making decisions, i.e., right for the right reasons.

2) Robust: The model should be robust to some situations with only low-quality training data (e.g., training samples are biased, noisy, or limited).

3) Universal: The model design is relatively universal, i.e., it is expected to be effective for various tasks.

Meanwhile, with the rapid development in pretrained models, such as the appearance of Large Language Models (LLMs), Stable Diffusion, we are also very interested in several releveant cutting-edge directions:

4) Building more explainable, robust, and universal vision models with the help of pretrained models (LLMs, diffusion models).

5) Designing more efficient and stronger multimodal LLMs.

6) The inherent weaknesses in existing LLMs and diffusion models.
