Bohao Xing

Junior Researcher (Ph.D. Candidate) · LUT University, Finland

Welcome to my academic homepage.

I am a Ph.D. candidate at the Computer Vision and Pattern Recognition Laboratory (CVPRL), LUT University, Finland. I am supervised by Prof. Heikki Kälviäinen, with Prof. Xin Liu as co-supervisor. I also collaborate closely with Prof. Guoying Zhao and Prof. Zitong Yu.

I received my M.Sc. and B.Eng. degrees from Tianjin University, China, in 2024 and 2021, respectively.

My research focuses on affective computing and multimodal large language models, with an emphasis on privacy-preserving and trustworthy emotion understanding.
