  • Investigation of resting-state brain connectivity with multi-modal imaging approaches (fMRI, MEG, and EEG).
  • Characterization and modeling of the hemodynamic response to neural activity, including the effects of drugs such as caffeine.
  • Development and optimization of arterial spin labeling MRI methods for the non-invasive measurement of cerebral blood flow.
  • Design and analysis of experiments for functional MRI (fMRI), with an emphasis on statistical optimization, nonlinear signal processing, and physiological noise reduction.
