EAS Remembers Wilfred D. (Bill) Iwan

11-02-20

Wilfred D. (Bill) Iwan, Professor of Civil Engineering, Emeritus, passed away on October 29, 2020. He was 85 years old. Dr. Bill Iwan received all his degrees from Caltech, B.S. in 1957, M.S. in 1958, and Ph.D. in 1961. He joined the Caltech faculty in 1964 and became Professor Emeritus in 2004. He served as the Executive Officer for Civil Engineering and Applied Mechanics, 1980-86. Dr. Iwan’s research focused on fundamental areas of mechanics, understanding and characterization of strong earthquake ground motion, analysis and monitoring of the response of structural systems subjected to extreme events, and public policy regarding disasters. His research achievements include the development of methods to represent complex nonlinear structures with simpler linear systems, the development of practical methods for earthquake-resistant design, and the development of simplified methods for the analysis of seismic isolation systems for critical equipment. In 1979, he proposed an earthquake early-warning system for urban regions. Dr. Iwan was elected to the National Academy of Engineering in 1999 “for research on seismic performance of structures, and for leadership in earthquake hazard mitigation and improvement of public safety.” He was a Distinguished Member and Fellow of the American Society of Civil Engineers (ASCE), which awarded him the Nathan M. Newmark Medal (1997), William H. Wisely Award (2006), and Theodore von Karman Medal (2013). In recognition of his distinguished service, the California Earthquake Safety Foundation awarded him the 2002 Alfred E. Alquist Medal “for his lifetime of service to the profession of structural engineering and its application to the safety of the people of California and the world". [Caltech story]

EAS Remembers James J. Morgan

09-21-20

James (Jim) J. Morgan, Marvin L. Goldberger Professor of Environmental Engineering Science, Emeritus, passed away on September 19, 2020. Dr. Jim Morgan came to Caltech in 1965 as Associate Professor of Environmental Health Engineering. After 35 years of distinguished service to the Institute, he became emeritus in 2000. He served as the Academic Officer for Environmental Engineering Science, 1971-72, Dean of Students, 1972-75, Executive Officer for Environmental Engineering Science, 1974-80 and 1993-96, Acting Dean of Graduate Studies, 1981-84, and Vice President for Student Affairs, 1980-89. Professor Morgan’s research was concerned with the chemistry and technology of water treatment, the scientific basis for establishing criteria and standards for water quality protection, and manganese in fresh and marine waters. He was renowned as a caring teacher and mentor to generations of students and scholars. His book on Aquatic Chemistry, which he co-authored with his advisor Werner Stumm, remains the standard reference on the subject (cited more than 25,000 times) and has become a worldwide classic. He received numerous awards and honors, including election to the National Academy of Engineering and the Athalie Richardson Irvine Clarke Prize for Water Science and Technology from the National Water Research Institute. Jim Morgan and Werner Stumm were awarded the Stockholm Water Prize in 1999. [Caltech story]

New Chip-Based Laser Gyroscope Measures Earth's Rotation

03-05-20

Optical gyroscopes are used in applications such as aircraft navigation systems, while MEMS gyroscopes are found in devices like smart phones. Kerry J. Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics; Executive Officer for Applied Physics and Materials Science, has developed an optical gyroscope that combines some of the best characteristics of each into one device. "For more than 20 years, researchers have speculated about placing optical gyroscopes onto a chip very much like the highly successful MEMS gyroscopes. But until recently, there have been very few compelling experiments," Vahala says. [Caltech story]
