Interests

My research focuses on techniques for analyzing and interpreting functional neuroimaging data.

Projects

Current project areas include: (i) methods for analyzing the temporal dynamics of large-scale brain networks; (ii) multimodal imaging (EEG-fMRI) of brain activity across vigilance states; and (iii) neural and physiological basis of spontaneous fMRI signals; (iv) techniques for improving fMRI signal quality.
