Jason earned his Masters in Computer Science in 1992 and immediately started working at Lawrence Berkeley Lab on a wide variety projects. Jason was involved in many of the early quality-of-service (QoS) network tests with Van Jacobson in 1994, when Jacobson was the head of the Network Research Group at Berkeley Lab. Jason has worked on some of the first gigabit test beds, including the Multidimensional Applications and Gigabit Internetwork Consortium (MAGIC) project in 1993, Bay Area Gigabit Network (BAGNet) in 1995 and National Transparent Optical Network (NTON) in 1997. He also worked with the Advanced Internet Research (AIR) group at the University of Amsterdam on 10-Gbps transatlantic links in 2002. Recently Jason has focused his attention on Security and how to better monitor and react to threats on the higher bandwidth links in use today in scientific computing (400Gbps).
