Christopher W. Rice is Vice President of Advanced Technologies and Architecture, overseeing research and advanced development in networking and IP network management, network virtualization, big data, speech and multimedia technologies, information systems and visualization, algorithms and optimization, and scalable, reliable software systems.

Chris was previously an Assistant Vice President within AT&T Labs Research, where he was responsible for platform and services incubation.  His areas of research included broadband wireless network architectures, IMS service platforms research, network performance and measurement research, application management research, and new IP services research.  He has helped successfully launch three services into the marketplace based on his team's research. Chris has over 30 patents in his name and in 2005, was awarded the AT&T Distinguished Scientist Award.

In 1995, he joined then AT&T Bell Labs to focus on wireless and broadband communication systems. He worked on satellite communication systems, broadband data communication systems, and led development efforts for a digital radio-based, pico-cellular base-station, which provided in-building, mobile voice communication on standard cellular phones.

Chris graduated Summa Cum Laude from Virginia Tech with a BSEE/MSEE and completed his MBA from the University of Central Florida while working full-time.  He performed post-graduate work with the WINLAB Center of Wireless Excellence at Rutgers University and received a Graduate Certificate in Wireless Information Networks.

Projects
Connecting Your World, The need to be connected is greater than ever, and AT&T Researchers are creating new ways for people to connect with one another and with their environments, whether it's their home, office, or car.

Enterprise Federation, By connecting two organizations with separate systems, workers can make a seamless connection between calendars, and presence information so that hybrid teams can work together more easily.
