Faculty Profile

Prof. DOU Weibei joined Tsinghua University in 1995 and created the Multimodal Data Processing Systems Lab (MMDPS Lab) under Department of Electronic Engineering. She is working on multisensor and multimodal signal processing systems, especially focus on multimodal data and brain neural information mining. It extents to theory, application and system design, three research domains, including of specific information extraction, information fusion-based decision,  evaluation and prediction modeling, etc. which are in theory research domain.  In application research domain, the structure MRI (sMRI), functional MRI (fMRI), diffusion tensor MRI (DTI) and electroencephalogram (EEG) signals, which acquired both from patients and health persons, are combined for finding the biomarkers of treatment effect, and for establishing the models of neurorehabilitation evaluation and prediction, exceptionally used for individual patient. The network science, including graphic and topological theories, are used for building both static and dynamic brain network model, and  for guiding topological data analysis and spatio-temporal measurement combined  structural and functional features of brain. The inverse EEG methods for source reconstruction or source localization are also studied for making the joint brain network analysis of sMRI, fMRI, and EEG (both electrode and source space). Evidence theory, statistical learning theory, deep learning models, etc. are applied for designing the multimodal information fusion systems, and for making the decision of neurorehabilitation predictors. Some research fruits have been used to study the altered brain volume, microstructure metrics and functional connectivity features in multiple system atrophy; zolpidem-related alterations and prognostic value in disorders of consciousness; Brain-Computer Interface Training in Stroke Patients; Microstate-specific functional connectivity and stroke-related alterations in Brain dynamics; Non-concomitant cortical structural and functional alterations in sensorimotor areas following incomplete spinal cord injury, etc.

She has been teaching some courses for undergraduate and graduate students since 1999, such as “Digital Signal Processing”,  “Experiment and Design of Signal Processing”, "Systems Design based on Digital Signal Processors",  “Digital Video and Audio Signal Processing”, “Architecture Analysis of Digital Signal Processing Processor”, "Audio Signal Prodessing Systems " . She has published more than 100 academic articles which have been cited at least 1200 times by other scientists. She has been awarded at least 20 Patents for Invention, and she has supervised 5 Ph.D. students and more than 25 M.Sc. Students
