• Research Associate, Department of Biomechanics, University of Nebraska at Omaha

• Currently working on the project “Function of spinal locomotor center during transspinal stimulation after spinal cord injury”. I investigated the actions of non-invasive transspinal stimulation over the thoracolumbar region at different intensities and frequencies on spinal reflexes and muscle activity at rest and during walking.
