Introduction

Dr. Hany Elgala is an Assistant Professor in the Computer Engineering Department, College of Engineering and Applied Sciences. Before moving to SUNY Albany, he was a Research Professor at Boston University (BU). There, he was the co-leader of the Multimedia Communications Lab (MCL) and the Communications Testbed leader at the National Science Foundation (NSF) Smart Lighting Engineering Research Center (ERC). From 2010-12, he was the co-leader of the Cellular and Wireless Communications (CWC) Lab at Jacobs University in Germany. There, he coordinated two industrial projects with Airbus Germany and the European Aeronautic Defense and Space Company (EADS) to realize high-speed optical wireless networks in airplane cabins. He is the author or co-author of approximately 50 publications or patents in the area of optical wireless systems.
