Dr. Ram Ramanathan is Chiefl Scientist at goTenna, where he architects, analyzes and help evolve networking protocols for goTenna off-grid device. Prior to that, he was Principal Scientist at BBN Technologies where he helped develop and prototype new technologies, primarily in wireless computer networks.  Ram's current research areas broadly include wireless networks, network analysis and control algorithms, and network science. Over the course of his career, he has made contributions to the areas of scalable routing, topology control and the use of directional antennas in multihop networks and led several projects for the DoD, in particular DARPA. 

Ram has published widely in international journals and conferences, including best paper award winning papers at IEEE MILCOM, IEEE INFOCOM, and ACM SIGCOMM. He has served on the program committees of several conferences including MobiCom, Mobihoc and Infocom, and was the TPC co-chair of Mobicom 2007. Ram has served on the editorial boards of IEEE Transactions on Mobile Computing (TMC) and Ad Hoc Networks journal, and was the Associate Editor-in-Chief of TMC. Ram received his Bachelor of Technology in Electrical Engineering from the Indian Institute of Technology, Madras, and received his M.S and Ph.D degrees in Computer and Information Sciences from the University of Delaware. He is a Fellow of the IEEE. Here's the full CV.
