While at DARPA, he led efforts advancing modern parallel computer architecture and associated Unix-based systems software, with lasting influences on the design of modern large-scale computing. In the late 1980s he helped advance a research partnership among federal agencies that continues as, the Networking and Information Technology Research and Development Program.
