Prof. Rohat Melik\, TOBB-ETÜ\n\nTopic: "Modulat ion of Ion Concentration In-Vivo"\n\nLocation: Middle East Technical Unive rsity\, Ankara\, Turkey\n\nAbstract: Our motion and behavior are as a resu lt of the change of the cellular membrane potential. Therefore\, by contro lling the membrane potential in-vivo\, we can control our motion and behav ior. In our work\, we applied extrinsic current and changed the ion concen tration gradient in-vivo hence\; changed the membrane potential in-vivo. T herefore\, we proposed and developed two fundamental technologies: changin g ion concentration gradient in-vivo and changing membrane potential in-vi vo. We used these fundamental technologies for therapeutics of neurologica l disorders. Approximately 6 million people are paralysis in US (1.9%). Co nventional Functional Electrical Stimulation (FES) aims to restore neurolo gical functions such as standing\, ambulation etc. However\, there is no w idely acceptable FES system because of high-energy expenditure and stimula tion of nearby sensory nerves\, causing pain. By using our novel electroch emical stimulation and blocking method\, we modulated ion concentration ar ound the sciatic nerve of a frog in-vivo using ion-selective membrane (ISM )\, hence\; lowered the stimulation current therefore decreased the energy expenditure. We also lowered the blocking current as a result localized s timulation and reduced pain.\n\nBio: Dr. Melik is currently an Assistant P rofessor in the Department of Electrical and Electronics (EE) Engineering at TOBB University of Economics & Technology\, Ankara\, Turkey. He receive d B.S. degree in Electrical and Electronics Engineering (major) and in Int ernational Economics (minor) from Middle East Technical University (METU)\ , Turkey in 2004. In his Ph.D. study\, Dr. Melik has worked on smart ortho paedic implants for early-diagnostics of orthopaedic traumas. In 2010\, he received his Ph.D. in Electrical and Electronics Engineering from Bilkent University\, Turkey. He worked as a postdoctoral fellow in the Department of Electrical Engineering and Computer Science at Massachusetts Institute of Technology (MIT) in 2011-2012. Since 2013\, he continues his career as an academic at TOBB University of Economics & Technology. His research in terest is particularly in implantable electronics\, which has clinical app lications in real life especially for the therapeutics of neurological dis orders. He is the recipient of Leopold B. Felsen Award for Excellence in E lectromagnetics.\n\nSpeaker(s): Asst.
