Geoff Mulligan grew up in the Bay Area and graduate from Gunn High School. While in High School Geoff worked for HP and NASA Ames Research Center. He graduated 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 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 ("Father of the Internet") 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 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.
Geoff left the Air Force after 11 years 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. 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.
Subsequently, Geoff joined Sun Microsystem's Internet Engineering Group. 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. This team of 5 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.
Geoff joined Invensys in early 2001 is Chief Scientist for the Home Controls Division working on resource and energy management technology including web based tools, home gateway design and development and low power, low speed, low cost RF. He help found was on the original BOD of the Zigbee Alliance. He then took over engineering responsibility for Invensys Building Systems and designed the first IPv6 based sensor network.
Geoff is currently consulting to a number of large companies in a the areas of RF/RFid technologies, Internet protocols, IPv6, sensor networks, computer security and gateway design. He is chair of the 6LoWPAN working group in the IETF and the IPv6 task group in the Zigbee Alliance.
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.
