EMERALD HONORS WINNERS
and investigating the human space frontier. His pursuits in both areas have always been complementary which ensures gains to both, acquiring skills that are transferable to a variety of complex problems facing NASA and the engineering world. He is also involved in several organizations including the University of California, Los Angeles Mechanical and Aerospace Engineering Department Alumni Advisory Board, the University of Southern California Center for Engineering Diversity, Human Factors and Ergonomics Society, International Council on Systems Engineer- ing, The Mars Society, Mars Desert Research Station, Space Tourism Society, Latin America Space Association, and Club Libertad, a Peruvian organization that sponsors kids’ foundations and promotes Peruvian culture in the United States. Diaz is also a member of the Orange County Youth Motivational Task Force, a partnership of local businesses and high schools that aims to reduce the high school dropout rate. As part of the youth moti- vational task force, Diaz goes to elementary and high schools to talk to students about the value of education, the importance of staying in school and living your dream.

satellites flying over the night sky. Time and again during his 30-year career at Boeing and the Jet Propul- sion Laboratory, Ih has contributed to the advance- ment of people and technology in the aviation and aerospace industry. This is reflected in the many accomplish- ments he has earned over the years, including seven patents, three Boeing Special Invention Awards (pre-

harles Ih has had a lifelong fascination with space. Growing up in Taiwan, he recalls watching Apollo 11 land on the moon in 1969 and the light spots of
ate Technical Fellow, a 2009 Boeing Frontiers innovator figure, American Institute of Aeronautics and Astronautics (AIAA) Fellow, AIAA Committee member and the technical chairman for the 2012 AIAA Modeling and Simulation Technologies Conference. Ih came to Boeing in 1996 from the Jet Propulsion Laboratory, where he supported high-profile programs such as the Space Shuttle and the International Space Station. Ih was also dynamics lead in the Galileo Control Systems group, contribut- ing to the well-known spacecraft that reached Jupiter. Several of Ih’s inventions have contributed to making complex space systems possible, from NASA space exploration to conveniently sized, portable satellite phones. As an associate technical fellow, Ih leads a team that is solving the most challenging on-orbit anomalies across Boeing’s domestic and international custom- ers. This work is key to maintaining customer satisfaction, revenue, and also to the training of newly graduated engineers. Ih earned his bachelor’s degree in Mechanical Engineering from Taiwan’s National Cheng Kung University in 1974 and traveled to the United States. There, he earned a master’s in Mechanical Engineering from Northwestern University in 1979 followed by a Ph.D. in Control Engineering from the University of California, Los Angeles, in 1985. Three years earlier, he joined NASA’s Jet Propulsion Laboratory and for the first eight years worked on control analysis. Ih’s contributions advanced a wide range of systems including the Space Shuttle and the International Space Station. His work on station assembly, shuttle docking, and astro- naut motion also laid a foundation for work that still continues at NASA. As dynamics and deputy analysis lead in NASA’s Galileo Control Systems, his contributions included analysis of Gali- leo control and dynamic systems, software update and testbed evaluation. He once designed a thruster cycle to rescue the $1.2 billion Galileo from catastrophic engine explosion and presented the story at “Space Ops 2006” hosted by aerospace experts at the International Committee on Technical Interchange for Space Mission Operations and Ground Data Systems. At Boeing since 1996, Ih continues to contribute to earth-orbiting satellites im- pacting the public’s lives. He has revolutionized the Boeing Sun acquisition algorithm using reaction wheels that tremendously increased the spacecraft safety and saved fuel. This technology is now used across Boeing’s space fleet with a positive impact on Boeing’s multi-million-dollar space business. He also led control of the deployment of the unprecedentedly large antennas. The fight data of deployments duplicated his analysis results, linking to very successful missions and the win of subsequent contracts. Ih became a Boeing Associate Technical Fellow in 2004, a go- to resource for design, analysis, test and mission operation of control systems. He won a position on the AIAA Modeling and Simulation Committee in 2008, and both Ih and the committee have enhanced capabilities of aerospace modeling and simula- tion by organizing international conferences. Ih has 42 publica- tions which are widely quoted by the aerospace community. He was selected an AIAA Associate Fellow in 2010. Active in his church, he helped set up study groups in Chinese Catholic com- munities all over Southern California for more than 15 years with hundreds of students. He has also been leading a singing group, The Flying Seeds, for eight. They primarily step out of the church and serve people of all races and ages everywhere.
