The purpose of my research is to develop fundamental understanding of the cortical control of the human hand and upper limb. My research program is focused on the somatosensory contributions to motor control; human hand control is profoundly dependent on the integrity of somatosensory input that arises from touch and muscle receptors. Multiple cortical areas receive and process somatosensory input yet little is known about the role of these areas in the control of human hand movement. My research program is primarily focused on investigating the role of somatosensory loci in the control of hand movement in healthy and clinical populations. Students in my lab use a combination of neurophysiology techniques including transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging.
