Haotian Bai

PhD student at AI Thrust of HKUST (GZ)

Hello, my name is Haotian Bai(白皓天). I am currently pursuing a Ph.D. in computer vision, AI Thrust, at HKUST’s Guangzhou campus, supervised by Prof. Hui Xiong(熊辉).

For a deeper personal story, see my Musings.

My primary research interests are in 3D reconstruction, with a focus on Neural Radiance Field (NeRF), and its applications using multi-model data. I am also interested in robotics, specifically simultaneous localization and mapping (SLAM). For my work, see Work. My papers are accepted at prestigious AI conferences such as CVPR, ICCV, ECCV, and NeurIPS. I also serve as reviewers on well known journals including TPAMI, TOMM, and TIP. Please feel free to comment on Github for further discussion on my works.

In my spare time, I enjoy cooking, playing basketball, listening to music, and learning about starting a business.

I’m currently a core founder of HoloSoul (灵映科技), building an emotional AI companion that blends voice, vision, and long-term memory to stay present for people we care about http://holosoul.ai/.
