Neurological disorders and traumatic injuries disrupt the bidirectional connection between the brain and the body, resulting in deterioration of both the sensory and motor systems. My long-term research goal is to develop technologies that restore the often-overlooked afferent sensory connection between the body and the brain via a spinal-neural electrical interface.

Spinal cord stimulation (SCS) – an FDA-approved therapy – has been used for chronic pain management for several decades . Several studies have recently explored its potential role in rehabilitation research by showing that SCS can repair injured locomotor circuits in patients with spinal cord injury. Yet the potential role of SCS in treating neurological disorders by directly modulating cortical circuits remains poorly understood. To fill this gap in knowledge and based on an underlying vision — to develop SCS as a novel therapeutic and sensory transmission channel to the brain — I have sought to investigate the following two research questions:

1) Can spinal cord stimulation create artificial sensory experiences?

2) Can spinal cord stimulation treat neurological disorders?
