Title: Low-Power, High-Performance, and Smart Circuits and Systems for Diagnosis and Treatment of Neurological Disorders

Speaker: Hakan Töreyin

Date/Time: December 15, 2015 – 10:40

Place: FENS G032

Abstract: According to the World Health Organization, around one billion people worldwide are affected by neurological disorders, ranging from Parkinson’s Disease to peripheral neuropathy. Conclusive diagnosis of many of these disorders can only be made through tests requiring use of large, expensive, time-consuming, and uncomfortable tools; which cannot be operated outside the clinics. Therefore in many cases, patients are diagnosed and receive treatment only after they visit clinics when symptoms occur. An increasingly popular treatment option for many neurological disorders ranging from sensory losses to mental problems is electrical neuromodulation. Despite the collaborative research efforts bringing engineers and clinicians together towards improving the clinical outcomes from neuromodulation treatment; engineering challenges to designing energy-efficient and unobtrusive systems achieving closed-loop operation and improved-selectivity of stimulation pathways, still remain to be tackled. The focus of this talk will be on creating a new class of wearable and implantable sensing and neuromodulation systems that could be used by minimally-trained users in uncontrolled settings; thereby potentially enabling timely diagnosis and effective management of neurological disorders. The talk will cover energy-efficient and robust circuits and systems design approaches to address the engineering challenges for building such high-performance and smart systems and research efforts for their translation into clinical use.


Bio: Hakan Töreyin received the B.S. degree in electrical and Electronics Engineering from Middle East Technical University, Ankara, Turkey, and the M.S. and the Ph.D. degrees in Electrical and Computer Engineering from Georgia Institute of Technology, Atlanta in 2007, 2008, and 2014, respectively. Dr. Töreyin is currently a postdoctoral researcher in the School of Electrical and Computer Engineering at Georgia Institute of Technology. In 2007-2008 he was a Fulbright Fellow and in 2012 he was awarded the Chih Foundation Research Award. At the IEEE EMBC 2014 Student Paper Competition, he was recognized as the North America Finalist and awarded the third prize. Dr. Töreyin’s research interests include energy-efficient circuits and systems design for wearable and prosthetic biomedical applications
