Chris Freeman is Professor of Applied Control within Electronics and Computer Science. His research interests include iterative learning and repetitive control theory and their experimental application to industrial systems and biomedical engineering. He has led the engineering component on large UK government funded grants which have developed a range of upper limb systems using robotic and Functional Electrical Stimulation (FES) technology that have each been trialled clinically with stroke patients. In this area his current focus is on biomechanics, motor learning and control, non-contact sensing, electrode-array based FES, and touch-table technology.
