DESCRIPTION OF WORK / BIOSKETCH
My research concerns spatiotemporal imaging of human brain function. I have applied integrated magnetoencephalography (MEG), electroencephalography (EEG), and functional magnetic resonance imaging (fMRI) to studies of cortical processing of visual information, including contrast patterns and visual motion. My research involves development of techniques for the analysis of multimodal biomedical imaging data, in particular, for the use of fMRI data to inform the source estimation (inverse problem) of MEG and EEG. Currently I am studying theoretical characteristics of the sensitivity of MEG and EEG sensor arrays and the cancellation of signals when multiple brain areas are active simultaneously. I am applying the source estimation methods to experimental data in collaboration with several researches how are using MEG/EEG/fMRI to study cognitive functions in normal and clinical populations, including dyslexia, obsessive-compulsive disorder, and migraine.
