Portrait of Gao Rui

Hello, I'm

Gao Rui

CS PhD Student at HKUST

I am a first-year PhD student in Computer Science at the Hong Kong University of Science and Technology (HKUST), supported by the HKPFS. You can call me Rui (Ray). I am a member of SmartX Lab, advised by Prof. Hao Chen.

Previously, I received my BS from Fudan University and my MS from UCLA. At UCLA, I conducted research in the HCI Lab under the supervision of Prof. Xiang Anthony Chen.

My current research centers on agentic AI for scientific discovery. I am also interested in AI for Science, vision-language models (VLMs), and reinforcement learning for large language models (LLMs).

My current research focuses on agentic AI for scientific discovery. Before starting my PhD at HKUST, I completed my MS in Electrical and Computer Engineering at UCLA, where I worked on molecule generation with large language models and reinforcement learning in the UCLA HCI Lab, supervised by Prof. Xiang Anthony Chen and collaborating with Dr. Youngseung Jeon. I also worked on vision-language models for autonomous driving at PlusLab, UCLA, supervised by Prof. Nanyun Peng and collaborating with Dr. Wenbo Hu and Dr. Jiachen Gu.

I received my BS in Biomedical Engineering from Fudan University, where I studied from 2020 to 2024. My undergraduate research included physiological signal classification and prediction under Prof. Yu Ma and Prof. Cuiwei Yang at the Fudan Biomedical Center. I was also very fortunate to join the AFAR Lab at the University of Cambridge, where I worked on multimodal models for depression research with Dr. Batuhan Sayis, under the supervision of Prof. Hatice Gunes.

Outside of research and studying, I enjoy playing badminton and jogging. Hong Kong is a great place for jogging, especially along the waterfront. I’m also a skilled FPS esports player (CS >> Val).
