My research focuses on the clinical development of human brain machine interfaces (BMIs).

Brain-machine interfaces involve decoding electrical signals form the brain to control external devices. For example, in paralysed patients, an important clinical goal is to be able record and decode activity from the motor cortex to control actions of a robotic limb, so that motor function can be recovered. My lab develops invasive BMI systems using surface electrocortical implants placed directly on the surface of the brain. We have successfully implanted these in patients, and continue to develop all aspects of these systems, including clinical, hardware and software components.

Currently we are developing a new fully implantable wireless system. Ultimately, we aim to develop general motor BMI systems that can be used in a range of patients with conditions such as tetraplegia, ALS and lock-in syndrome, to support restoration of motor and communication functions.
