Brief Introduction:

Xiaopeng Si, Ph.D., Professor, Doctoral Advisor, Director of multimodal brain cognition and intelligence (MBCI) Lab. Xiaopeng Si received the B.S. and Ph.D. degrees in Biomedical Engineering from Tianjin University and Tsinghua University, respectively. He was a visiting scholar in the department of Biomedical Engineering at Johns Hopkins University. Dr. Si currently works as a tenured full professor and is the director of the Multimodal Brain Cognition and Intelligence (MBCI) Laboratory at Tianjin University since 2018. His research interest includes brain cognition and intelligence, neural engineering and brain-computer interface (BCI), multimodal neural information acquisition and computing, etc. His group integrates multimodal neuroimaging (e.g., EEG-fNIRS, iEEG) with deep-learning techniques to elucidate human cognitive processes and to translate these insights into next-generation multimodal BCIs. He has led numerous national and international research projects, and his team’s work has been published in leading journals such as PNAS, IEEE T Affect Comput, IEEE J Biomed Health, IEEE T Neur Sys Reh, Biological Psychiatry, Expert Syst Appl, Cyborg and Bionic Systems, Cereb Cortex (Cover Article), J Neural Eng. The team won first prize in the 2022 World Robot Contest Affective BCI Competition (world No. 1), second prize in the 2023 World Robot Contest BCI Paper Competition (world No. 2), and second prize in the 2024 World Robot Contest Minimally Invasive BCI Competition.
