IEEE AP/MTT/EMC/ED TURKEY CHAPTER SEMINAR SERIES -- SEMINAR 67
06 March 2020 (13:40): IEEE AP/MTT/EMC/ED Turkey Seminar Series (S.67)
Speaker: Assoc. Prof. Sedat Nizamoğlu, Koç University
Topic: "Bioelectronic Neuron-machine Interfaces Controlled with Light"
Location: Middle East Technical University, Ankara, Turkey
Abstract: Bioelectronic devices controlling neurons show high promise for advanced treatments of a broad range of neurological disorders such as retinal degeneration, Parkinson’s and Alzheimer’s. Light is an excellent tool for communicating with biological systems, thanks to its high spatial and temporal resolution. In my speech, I will discuss how we can generate bioelectronic stimuli with optoelectronic devices to control neurons [1]. For this purpose, I will present innovative devices based on organics and nanomaterials with high light sensitivity [2]. I will also show that nanoscale charge control can provide photostimulation of neurons at low light level [3,4]. These findings bring new approaches to superior light-triggered bioelectronic control of neural activity.

Bio: Sedat Nizamoglu received his B.Sc. degree in Electrical and Electronics Engineering (EEE) in 2005, M. Sc. degree in Physics as a Valedictorian in 2007 and his Ph.D. in EEE in 2011 at Bilkent University. Immediately after graduation, he continued as a research fellow with a joint affiliation with Harvard Medical School and Wellman Center for Photomedicine, Massachusetts General Hospital in USA. Before joining Koç University, he was a faculty member at Özyeğin University. His research focuses on the demonstration of innovative bioelectronic and optoelectronic devices and interfaces for the applications to energy, medicine, and environment. He has published more than 60 research papers in prestigious journals including Nature Communications, Nature Photonics, Advanced Materials and Nano Letters. He was recognized by MIT Technology Review as Innovator Under 35 Turkey. He received Encouragement Award by TUBITAK (Turkish NRF), Outstanding Young Scientist Award by Turkish Academy of Sciences and Science Academy. In addition, he was awarded an ERC (European Research Council) Starting Grant.
