Dr. Abeyratne earned a PhD degree from the Biomedical Engineering and Science Inst, Drexel University, Philadelphia, USA, and a Master's Degree in Electrical and Electrical Engineering from Tokushima U, Tokushima, Japan. His Bachelor's degree is from U. Peradeniya, Sri Lanka, in the field of Electrical and Electronic Engineering. He holds two Grad. Certs in Higher Education and Pediatric Sleep Science respectively from The Univ of Queensland and The U of Western Australia School of Medicine. Dr. Abeyratne's expertise is in areas of medical instrumentation and signal processing. In particular, he has contributed to medical ultrasound imaging and tissue characterization; Electrophysiological signal acquisition and processing, and novel technologies for the diagnosis of sleep and respiratory disorders. Dr. Abeyratne maintains an active research interest in appropriate technologies for remote area health.
