Talk Title: Addressing Spectrum Scarcity through Optical Wireless Communications
Abstract: Rapid increase in the use of wireless services over the last two decades has lead the problem of the radio-frequency (RF) spectrum exhaustion. More specifically, due to this RF spectrum scarcity, additional RF bandwidth allocation, as utilized in the recent past, is not anymore a viable solution to fulfill the demand for more wireless applications and higher data rates. The talk goes first over the potential offered by optical wireless communications to relieve spectrum scarcity. It then summarizes some of the challenges that need to be surpassed before such kind of systems can be massively deployed. Finally the talk offers an overview of some of the recent results for the determination of the capacity of optical wireless channels.
Biography: Mohamed-Slim Alouini (S'94, M'98, SM'03, F'09) was born in Tunis, Tunisia. He received the Ph.D. degree in Electrical Engineering from the California Institute of Technology (Caltech), Pasadena, CA, USA, in 1998. He served as a faculty member in the University of Minnesota, Minneapolis, MN, USA, then in the Texas A&M University at Qatar, Education City, Doha, Qatar before joining King Abdullah University of Science and Technology (KAUST), Thuwal, Makkah Province, Saudi Arabia as a Professor of Electrical Engineering in 2009. His current research interests include the modeling, design, and performance analysis of wireless communication systems.

Speaker: Marilyn Wolf, Georgia Institute of Technology
Talk Title: Service-oriented Architectures for Cyber-physical Systems
Abstract: Service-oriented architectures are widely used in information processing and Web technologies to provide scalable access to resources in distributed systems and extensible applications. However, many traditional service-oriented architectures are designed for transaction processing. In contrast, cyber-physical systems used for real-time control require quality-of-service constraints and graceful handling of failures to provide requested services. Our group is developing extended service-oriented models for use in smart energy grids and other applications. We will describe our work in service-oriented architectures, including model-based design and simulation.
Biography: Marilyn Wolf is Rhesa S. "Ray" Farmer Distinguished Chair in Embedded Computing Systems and Georgia Research Alliance Eminent Scholar at the Georgia Institute of Technology. She received her BS, MS, and PhD in electrical engineering from Stanford University in 1980, 1981, and 1984, respectively. She was with AT&T Bell Laboratories from 1984 to 1989. She was on the faculty of Princeton University from 1989 to 2007. Her research interests include cyber-physical systems, embedded computing, embedded video and computer vision, and VLSI systems. She has received the ASEE Terman Award and IEEE Circuits and Systems Society Education Award. She is a Fellow of the IEEE and ACM and an IEEE Computer Society Golden Core member.

Talk Title: Large-Scale Organic Neural Interface Devices
Abstract: Recording from neural networks at the temporal resolution of action potentials is critical for understanding how information is processed in the brain. We developed an organic, conformable, biocompatible and scalable neural interface electrode and transistor arrays that can record both Local Field Potential (LFP) and extracellular action potentials without penetrating the brain surface. We recorded spiking activity in both rodent experiments and intra-operatively in patients undergoing epilepsy surgery using a large-scale surface probe designed to enable localization of fine LFP activity and the underlying neuronal entrainment. Large-scale, chronically recorded data generated by these devices has broad applicability to the understanding of physiologic and pathologic network activity, control of brain-machine interfaces, and therapeutic closed-loop devices.
Biography: Dion Khodagholy is a fellow at the Simon's Society of Fellows and a postdoctoral research associate in Prof. GyoÌrgy BuzsaÌki's laboratory at New York University Langone Medical Center (NYULMC). He received his Masters degree from University of Birmingham (UK) in Electronic and Communication Engineering. This was followed by a second Masters degree in Microelectronics at Ecole des Mines (France) combined with industry experience at Microelectronic Center of Provence. He attained his Ph.D. degree in Microelectronics at the Department of Bioelectronics (BEL) of Ecole des Mines with Prof. George Malliaras. At BEL, he focused on understanding organic semiconductor device physics and developing organic-based devices to interface with biology. His postdoctoral research at NYULMC is focused on three main domains: (i) design and development of large-scale, organic material-based neural interface devices; (ii) analysis of neural data acquired by these devices to understand large-scale neural network function; (iii) translation of these advancements to neural data acquisition systems in patients with epilepsy. His research explores the interface of electronics and the brain in the context of both applied and discovery sciences, with the ultimate goal of innovating in device engineering and neuroscience methods to improve diagnosis and treatment of neuropsychiatric disease.
