Geoff Mulligan graduated in 1979 from the United States Air Force
Academy with a Bachelor of Science degree in Computer Science, and was
selected as one of the few junior officers to be assigned to the First
Information Systems Group at the Pentagon. While there, Geoff brought
the first UNIX system on-line to the Arpanet (the "grandfather of the
Internet") for the Office of the Secretary of Defense. Geoff also
consulted on the design of the next generation of networks, the
Defense Data Network focusing on security and performance and designed
and directed installation of the nation's largest local area network
using cable TV technology.

Subsequently, Geoff was chosen to return to the Air Force Academy as
Division Chief of Network and Unix Systems where he oversaw the design
and installation of the Academy's local area network supporting over
4000 students and faculty and brought the Academy on-line to the
Defense Data Network. While at the Academy Geoff earned his Master's
in Computer Science from the University of Denver, taught
undergraduate computer science course at the Air Force Academy and
Chapman College and graduate computer science courses at the
University of Denver. He also consulted on network/system design and
security to SAIC and Telos.

Geoff left the Air Force in 1990 to join Digital's newly formed
Network Systems Laboratory, part of Digital Equipment. Geoff's primary
focus was on network security and an architect of the DEC SEAL
firewall. In addition, Geoff put together a number of courses dealing
with various subjects such as TCP/IP networking, electronic mail, and
networking tools. Geoff also worked on investigating new electronic
mail technologies to allow remote access. He was a member of the
multi-corporation Bay Area Gigabit network design team and the
original IPv6 protocol design team.

Geoff joined Sun Microsystem's Internet Engineering Group in 1992. He
was responsible for development and maintenance of the Solaris user
level TCP/IP utilities and kernel development. He also worked on the
design and support of Sun's Wide Area Network and the firewall complex
protecting enterprise systems. Geoff continued with the IPv6 design
team and provided the first PC based implementation, along with a
packet decoder and worked on the development of the IPv4/IPv6 border
gateway. Geoff joined Sun's Internet Commerce Group as a founding
member where he was a principal architect of Sun's premiere firewall
product -Sunscreen. During a sabbatical from Sun he helped start a new
Internet company, USA.NET. The primary product for this new company
was NetAddress . a permanent e-mail address and email-outsourcing
product. Geoff's responsibilities included overseeing the design and
development of the product in addition to managing the operations of a
private network supplying Internet access to over 6000 customers in
four states.

Geoff returned to Sun to complete the development of the next
generation of Sunscreen and added network address translation and
topology hiding technologies and was the group's Chief Technologist
and security products evangelist. He continued to do research into
network and system security, IP multicasting, and e-mail portability.

Geoff left Sun to co-found Geocast Network Systems where he was
responsible for operating system design and support and network
architecture for the evolving Internet multicast communication
technology the company was developing.  Through the work the team,
they demonstrated a working multicast transmission using satellite
transmission and were able to close an initial round of funding from
Kliener, Perkins, Mayfield and IVP.

Following Geocast Geoff co-founded Interosa and moved there as the
company's Chief Technology Officer and architect and subsequently
Chief Executive Officer. Interosa was building a new and revolutionary
policy based privacy technology for digital content and an email
privacy system based on this new software. In July of 2000,
InterosaMail was chosen by the Electronic Messaging Association as the
Best of Show for Emerging Technology, but due to funding issues the
company was shut down in November of 2000.

Currently Geoff is Chief Scientist for the Home Controls Division of
Invensys where is working on resource and energy management technology
including web based tools, home gateway design and development and low
power, low speed, low cost RF (aka 802.15.4 and Zigbee).

He holds a number of patents in computer and network security and
electronic mail. He is the author of the book "Removing the
Spam,. published by Addison Wesley in March of 1999. His book was
selected as one of the best security books of 1999. In 1997 Geoff was
called to testify before the Congressional Committee on Science about
electronic commerce and computer security and in 1998 he was an expert
witness in the Amazon vs. Barnes & Nobel '1 click' patent case.

Geoff has long held to the philosophy that the key to success in our
rapidly changing society is to stay close to the cutting edge, and to
keep pace with evolving technology. He believes that one can never
stop learning and sees the potential in new ideas, even before the
industry accepts them as standards. Geoff is known for his
far-reaching knowledge on a vast array of computer subjects and is
respected by his colleagues for his insight into established and
emerging fields and has been long regarded as an expert in
Inter-Network Technology.
