EAS Remembers Roddam Narasimha
12-15-20
Caltech Distinguished Alumnus, Roddam Narasimha, passed away on December 14, 2020, at the age of 87. Dr. Narasimha received his Ph.D. (1961) in Aeronautics from Caltech. He was a faculty member at the Indian Institute of Science, and more recently, the Year-of-Science Chair Professor at the Jawaharlal Nehru Centre for Advanced Scientific Research. He was also a former director of the Indian National Aerospace Laboratories. Narasimha was a Clark B. Millikan Visiting Professor and a Sherman Fairchild Distinguished Scholar at Caltech. He made outstanding and wide-ranging scientific contributions in fluid mechanics and aerodynamics, and was internationally known for his research in turbulence with applications in geophysical fluid dynamics and atmospheric sciences. Narasimha was a foreign member of the U.S. National Academy of Engineering and the National Academy of Sciences, and a fellow of the Royal Society. [Obituary]

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]

Jakob van Zyl, Senior Faculty Associate in Electrical Engineering and Aerospace, passed away on August 26, 2020 at the age of 63. He came to Caltech in 1982 and received his M.S. and Ph.D. in Electrical Engineering in 1983 and 1986, respectively. He joined JPL in 1986 and retired in 2019 as the Director of Solar System Exploration. He was world-renowned for his research in imaging radar polarimetry. He made pioneering contributions to the design and development of many synthetic aperture radar (SAR) systems, including SIR-C, SRTM, AIRSAR, TOPSAR, and GeoSAR. He held management roles at JPL including, Director for Astronomy and Physics (2006-2011), Associate Director of Project Formulation and Strategy (2011-2015), and Director of Solar System Exploration (2016-2019). He received many honors and awards, including an honorary doctorate from his alma mater, the University of Stellenbosch in South Africa in 2015 for his contributions to space missions, for being a good ambassador for Africa, and for inspiring young scientists and engineers in his home continent. Over the last two decades, he taught EE/Ae 157 Introduction to the Physics of Remote Sensing. He contributed in numerous ways to promote interactions between EAS and JPL.

Yuan-Cheng "Bert" Fung passed away on December 15th, 2019, at the age of 100. Dr. Fung received his Ph.D. (1948) in Aeronautics from Caltech and served on the GALCIT faculty until 1966. He then joined the faculty at the University of California, San Diego where he founded the Bioengineering program. He made ground-breaking contributions to our understanding of the mechanics of living tissues and is known as the father of Biomechanics. He was an elected member of all three branches of the National Academies: Sciences, Engineering, and Medicine. Dr. Fung received Caltech’s Distinguished Alumni Award in 1994. Among his many honors, he was awarded the National Medal of Science in 2000. [Full obituary, UCSD]
