Research Interests:

One of the major research activities in our laboratory focuses on the development of innovative methodologies for noninvasive functional neuroimaging. Emphasis is placed on development of high resolution spatio-temporal functional neuroimaging modalities and the investigation of cognitive processes in the brain. Of current interest is the investigation of electrophysiological neuroimaging using dense array EEG/ERP recordings and advanced imaging techniques to reconstruct neuronal source distributions within the brain. We are also investigating multimodal neuroimaging approaches integrating electrophysiological neuroimaging with functional magnetic resonance imaging. Another area of investigation is to develop brain-computer interface, providing a new communication channel between the brain and external environment.
