Biography

Dr. Xin Liu is a Tenured Associate Professor at the School of Psychology, Shanghai Jiao Tong University (2026–present). Prior to this, he served as an Associate Professor at LUT University in Finland (2021–2025) and as an Associate Professor at Tianjin University, China. He continues his affiliation with LUT University as an Adjunct Doctoral Supervisor.

He received dual Ph.D. degrees—one in Computer Science from the University of Oulu, Finland, supervised by Prof. Guoying Zhao, and another in Information and Communication Engineering from Xi'an Jiaotong University, China, supervised by Prof. Chun Qi. His academic journey includes research collaborations with Prof. Dacheng Tao at the University of Sydney as an Endeavour Research Fellow, and with Prof. Stefanos Zafeiriou at Imperial College London. He later returned to the University of Oulu as an Academy of Finland Postdoctoral Fellow, working alongside Prof. Guoying Zhao and Prof. Matti Pietikäinen at the CMVS group.

Dr. Liu's contributions to artificial intelligence have been recognized through numerous grants and awards. He has led multiple research projects funded by the National Natural Science Foundation of China, the Academy of Finland, the Finnish Ministry of Education, and CSC–IT Center for Science. His work has also received support from foundations and industry partners including the Finnish Foundation for Technology Promotion , the Nokia Foundation, the KAUTE Foundation, the Otto A. Malm Foundation, the Tauno Tönning Foundation, and the Riitta and Jorma J. Takanen Foundation. He was also the recipient of the prestigious Endeavour Research Fellowship awarded by the Australian Government. Dr. Liu is a Senior Member of IEEE and an active member of ACM, SPIE, ELLIS, and APA.

His research lies at the intersection of artificial intelligence and psychology, with a focus on developing objective computational methods and tools for emotion understanding and mental health assessment using computer vision and machine learning. His core interests include trustworthy affective computing and human-machine empathy, and he has made innovative contributions to multimodal large language models for emotion analysis, micro-gesture and micro-expression analysis, and remote physiological signal detection. He has published over 80 papers in leading international journals and conferences, including IEEE TPAMI, IJCV, CVPR, and ICLR, and holds more than 20 patents. He currently serves as an Associate Editor for several international journals, including IEEE Transactions on Multimedia.
