His Expertise

A scientist, educator, and technologist with hands-on experience, Dr. Lavian has served as Principal Investigator (PI) for three DARPA (Defense Advanced Research Projects Agency) projects and for an undisclosed federal agency’s classified wireless research project. In addition, Dr. Lavian has directed a networking computation project for the US Air Force Research Lab (AFRL) and pioneered a number of technical firsts, among them leading and developing the first network resource scheduling service for grid computing; managing and engineering the first demonstrated transatlantic dynamic allocation of 10Gbs Lambdas as a grid service; and developing and successfully demonstrating the first wire-speed active network on commercial hardware. During more than a decade in scientific and research roles at Nortel Networks he also created and chaired its Enterprise Data Network Patent Committee.
