Assistant professor, University of California, Berkeley
Invented algorithms for simulating natural phenomena such as splashing water and explosions, for use in movies, video games, and advanced training simulations.
Constructs more-intuitive human-computer interfaces. The Spanish native’s projects include a smart office that can recognize what its occupants are doing and a system that lets users interact with computers via hand gestures.
Visiting research scientist, Mitsubishi Electric
Built large computer display systems that seamlessly combine images from multiple projectors. The computer scientist’s image-processing and graphics research may lead to new applications in entertain-ment, image-guided surgery, and user interfaces.
Senior technical consultant, AT&T
Created tools for monitoring and automatically managing Internet traffic on large networks. The computer scientist’s innovations are used in several systems, including AT&T’s commercial backbone network.
Founder and chief technology officer, Millennial Net
Designed extremely-low-power wireless-sensor networks at Burlington, MA, startup. The company’s dime-sized sensor nodes can be used for environmental monitoring, surveillance, and health-care applications where inexpensive, long-term data collection and control are key.
Lecturer, Australian National University
Built tiny generators for wireless sensor networks that convert low-level background vibrations into electricity, eliminating the need for batteries.
Professor, Carnegie Mellon University
Invents new forms of digital visualization. The professor of entertainment technology teaches game design and heads simulation projects, including one that helps firefighters deal with terrorism.
Department head, Philips Electronics
Helped develop blue-laser optical-disc storage systems with much greater capacity than today’s DVDs. The discs are now being introduced commercially.
