Geoff Mulligan

He continued with the IPv6 design team and wrote a PC-based implementation, called N6AFV, along with a packet decoder, and worked on the development of an IPv4/IPv6 border gateway.

[10] Mulligan further developed Sunscreen, adding network address translation, an internal Java interpreter and topology hiding technologies.

[11] In 1997, he created HZ.COM, an electronic mail information retrieval system for two-way pagers and early cellular phones.

When the HZ.COM domain was hijacked in 2002, the incident was featured in the International Corporation for Assigned Names and Numbers (ICANN) Security and Stability Advisory Committee's report of 2005.

[17] In 2001, Mulligan was hired by Invensys as the chief scientist for the Home Controls Division, where he worked on resource and energy management technology, including home gateway design and development, web-based tools, and low-power, low-speed, low-cost wireless networks such as the IEEE 802.15 standards marketed with the Zigbee trademark.

[18] He was one of the founding board members of the Zigbee Alliance[19] and was co-chair of the 6LoWPAN Working Group in the Internet Engineering Task Force (IETF).

In June 2013, Mulligan became one of the second round of Presidential Innovation Fellows, working at the National Institute of Standards and Technology (NIST) [4][21] and was co-creator of the White House's SmartAmerica Challenge.

The theme of the briefing was the need to protect the confidential nature of private communications and to ensure that stored proprietary data remains uncompromised.
