Jason Potas

Senior Lecturer

Dr Jason Potas is a neuroscientist interested in somatosensory (touch, proprioception and pain) and motor systems. He received his PhD training at the University of Sydney, Australia, before undertaking post-doctoral studies in various areas relating to neural injury. Before returning to academia at the Australian National University, he worked in industry in Brazil, and currently holds a senior lecturer position (neuroanatomy) at the University of New South Wales. Dr Potas leads an independent research team seeking to understand how somatosensory information is transformed through the nervous system. His laboratory projects, combining neuroscience, neurotrauma, machine-learning and biomedical and chemical engineering, aim to restore, mimic and/or augment sensorimotor systems.
