spinal cellular mechanisms underlying hyperactive reflexes and loss of motor control in human chronic spinal cord injury (SCI). In particular, she is interested in muscle activity and force production during involuntary movements (e.g. reflex responses) and voluntary movements (e.g. maximum strength) and is investigating differences within these motor control factors between individuals with SCI and individuals without neurological injuries. In addition, she is researching the impact of persistent cellular conductances that may contribute to these differences by using specific medications known to decrease these conductances in animal studies
