Recipient of Distinguished Alumni Award from the University of California, Santa Barbara (1995). Recipient of two Phi Kappa Tau awards - the Taylor A. Borradaile National Alumnus of the Year Award (1996) and the Nu Chapter Alumnus of the Year (1991) award. Recipient of the 2003 Excellence Award in Science and Technology, from the US Pan Asian American Chamber of Commerce. Recipient of the 100 Most Influential Asian Americans in the 1990¹s Award from A-Magazine (2000). Keynote Commencement Speaker for the Departments of Engineering at the University of California at Berkeley, and at Santa Barbara (1996). Invited lecturer on honeycomb material and bonded panels, and cure modeling of aerospace composite materials, at the Beijing Institute of Aeronautical Materials, and at the Changsha Institute of Technology, 5th Department, in the Peoples Republic of China (1988). Invited contributor to the International Encyclopedia of Composite Materials (1989). Listed in Who¹s Who in Science and Engineering (1990).

EXPERIENCE: Dr. Chiao graduated in 1987 from the University of California at Santa Barbara, and joined the Hexcel Corporation in Dublin, California. He worked for Hexcel until 1989, during which time he was involved in process, manufacturing, and engineering research on advanced aerospace materials. He worked on a joint NASA-JPL/Hexcel project to develop an optically correct, polymer composite precision segment reflector, for future space telescopes. He also worked on cure modeling and finite element analysis. In January of 1989 Dr. Chiao joined the Lawrence Livermore National Laboratory in Livermore, California, where he was involved in processing research for fabrication of filament-wound and thick-section aerospace composites, where he developed and demonstrated a mechanistic cure model for graphite fiber/epoxy composite material. An instrument-rated pilot, Dr. Chiao has logged over 2600 flight hours in a variety of aircraft.

NASA EXPERIENCE: Selected by NASA in January 1990, Dr. Chiao became an Astronaut in July 1991. He is qualified for flight assignment as a Space Station Commander, Space Station Science Officer and as a Space Shuttle Mission Specialist. His technical assignments to date include: Space Shuttle flight software verification in the Shuttle Avionics Integration Laboratory (SAIL); Crew Equipment, Spacelab, Spacehab and Payloads issues for the Astronaut Office Mission Development Branch; Training and Flight Data File issues; EVA issues for the EVA Branch. Dr. Chiao also served as Chief of the Astronaut Office EVA Branch. A veteran of three space flights, he flew as a Mission Specialist on STS-65 in 1994, STS-72 in 1996 and STS-92 in 2000. Dr. Chiao has logged a total of 36 days, 12 hours, 36 minutes and 5 seconds in space, including 26 hours and 19 minutes of EVA time in four space walks.

Dr. Chiao is assigned as Commander and NASA Science Officer of Expedition-10, scheduled to launch to the International Space Station aboard a Soyuz spacecraft in October 2004.

SPACE FLIGHT EXPERIENCE: STS-65 Columbia (July 8-23, 1994) launched from and returned to land at the Kennedy Space Center, Florida, setting a Federation Aeronautique Internationale flight duration record for P2 spacecraft. The STS-65 mission flew the second International Microgravity Laboratory (IML-2). During the 15-day flight the seven-member crew conducted more than 80 experiments focusing on materials and life sciences research in microgravity. The STS-65 mission was accomplished in 236 orbits of the Earth, traveling 6.1 million miles in 353 hours and 55 minutes. On this mission, Dr. Chiao became the 196th NASA Astronaut to fly in space and the 311th human in space.

STS-72 Endeavour (January 11-20, 1996) was a 9-day mission during which the crew retrieved the Space Flyer Unit (launched from Japan 10-months earlier), and deployed and retrieved the OAST-Flyer. Dr. Chiao performed two spacewalks designed to demonstrate tools and hardware, and evaluate techniques to be used in the assembly of the International Space Station. In completing this mission, Dr. Chiao logged a total of 214 hours and 41 seconds in space, including 12 hours and 57 minutes EVA time, and traveled 3.7 million miles in 142 orbits of the Earth. During this flight, Dr. Chiao became the first Asian-American and ethnic Chinese to perform a spacewalk.

STS-92 Discovery (October 11-24, 2000) was launched from the Kennedy Space Center, Florida and returned to land at Edwards Air Force Base, California. During the 13-day flight, the seven-member crew attached the Z1 Truss and Pressurized Mating Adapter 3 to the International Space Station using Discovery¹s robotic arm and performed four space walks to configure these elements. This expansion of the ISS opened the door for future assembly missions and prepared the station for its first resident crew. Dr. Chiao was the EVA/Construction Lead for this mission and totaled 13 hours and 16 minutes of EVA time in two space walks. The STS-92 mission was accomplished in 202 orbits, traveling 5.3 million miles in 12 days, 21 hours, 40 minutes and 25 seconds.
