Greg Finnis a senior computer scientist in the Computer Networks Division at the USC Information Sciences Institute. He received the B.S. degree in Physics in 1973 from Brandeis University and the M.S. in Computer Science in 1978 from the University of Southern California.

Greg joined ISI in 1979 and worked for Jon Postel as a researcher until 1991. During this period Greg developed the first IP suite for Xerox bitmapped workstations and was a principal developer of the first multimedia email system. In 1991 he became principal developer for the ATOMIC project under Danny Cohen. ATOMIC is believed to have been the first functional gigabit LAN, capable of combined send/receive speed of nearly 800 Mb/s.

He later became project leader for the Netstation project, which attempted to demonstrate that gigabit LANs allowed a workstation's primary peripheral devices to be attached to a network via IP/TCP rather than to a specialized internal bus. Toward that end the project demonstrated reliable transmission of 30K/datagrams-per-second, plus their acknowledgements between hosts. The demonstation of a functioning IP-based SCSI disk driver was a key step in what later beacme the IP-SCSI effort in the IETF.

Currently, his research interests lie in the area of virtual computer networks, in particular mechanisms for their automated creation. To that end he developed a language for defining virtual networks that is used both in the Xbone and Dynabone projects. He also has demonstrated that virtual networing can be applied widely and generally to enable application domains, such as geographic addressing and regional broadcast, that cannot be supported by the current Internet (see the preliminary draft GeoNet).
