Dr. Nina Bradley, PhD, is Associate Professor in the Division of Biokinesiology & Physical Therapy and the Department of Cell & Neurobiology at USC. She serves as the Director of the Motor Control Development Laboratory at USC, conducting research in early sensorimotor development. She is currently the Principal Investigator of an NIH R01 awarded by the National Institute of Child Health and Human Development entitled “Development and Control of Repetitive Leg Movements During Embryonic Development.” Her interest in early childhood development has been evident throughout her research career, as the PI of an NSF-funded research grant investigating the embryonic foundations of motor control development, as well as two research projects investigating prenatal development funded through the Zumberge Faculty Research and Innovation Fund. Dr. Bradley was also the recipient of the Pediatric Section Research Award from the American Physical Therapy Association.

“Development and control of repetitive leg movements during embryonic development”
The goals of the studies are to characterize the motor commands and kinematics for a distinct class of repetitive limb movements that emerge in the final days of embryogenesis. Studies will also determine when and how motion-dependent feedback uniquely shaped by environmental constraints begins to impact the motor commands and how the motor commands are impacted by changes in the rate of embryogenesis under different light conditions.
