Nivetha Karthikeyan Awarded Chang Career Exploration Prize

11-23-20

Caltech has awarded the third annual Milton and Rosalind Chang Career Exploration Prize to alumna Nivetha (Niv) Karthikeyan (BS ’20) for her proposed project “Intersections: Building Solidarity Through Community Archives,” which intends to construct and share a new online community archive recording how people of color have historically created alliances, coalitions, and communities with other racial minorities in the United States.

Solar Geoengineering May Not be a Long-Term Solution for Climate Change

11-23-20

Pumping aerosols into the atmosphere to reflect sunlight, thus cooling Earth, is one last-ditch method for dealing with climate change. According to new research, solar geoengineering may fail to prevent catastrophic warming in the long run. It would not prevent high atmospheric carbon dioxide concentrations from destabilizing low-lying clouds, opening the door to extreme warming. "Solar geoengineering ultimately may not fix the problem if high greenhouse gas emissions continue for more than a century," says Tapio Schneider, Theodore Y. Wu Professor of Environmental Science and Engineering; Jet Propulsion Laboratory Senior Research Scientist. [Caltech story]

Robotics Engineers Take on COVID-19

11-18-20

Methods that were originally created to help robots to walk and autonomous cars to drive safely can also help epidemiologists predict the spread of the COVID-19 pandemic. Professor Aaron Ames and colleagues took these tools and applied them to the development of an epidemiological methodology that accounts for human interventions (like mask mandates and stay-at-home orders). By utilizing the U.S. COVID-19 data from March through May, they were able to predict the infection wave during the summer to high accuracy. "This is the greatest health challenge to face our society in a generation at least. We all need to pitch in and help in any way we can," Ames says. [Caltech story]

Large Variations in Shaking in Los Angeles Basin

11-11-20

Using data from a network of 500 seismic stations across the Los Angels basin, researchers have revealed areas where the amplification of shaking in high-rise buildings is greatest. "We thought the amplifications would be south of downtown LA, but we didn’t see that,” Monica Kohler says. “We saw them elsewhere, where the basin is not deep, in West LA and the San Fernando Valley." Each building shakes differently during an earthquake. Studying those differences will help to improve building codes and practices and potentially save lives.

FUTURE Ignited

11-04-20

Nearly 200 undergraduates from more than 120 colleges and universities across the country joined Caltech for FUTURE Ignited, a virtual event that aimed to encourage students of color to pursue graduate studies in science and engineering. The goal of FUTURE Ignited is to diversify STEM with students of color who will go on to become incredible graduate students and scientific leaders in their respective fields. [Caltech story]

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]

Ultrafast Camera Films 3-D Movies at 100 Billion Frames Per Second

10-19-20

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has developed technology that can reach blistering speeds of 70 trillion frames per second, fast enough to see light travel. Just like the camera in your cell phone, though, it can only produce flat images. Now, Wang's lab has gone a step further to create a camera that not only records video at incredibly fast speeds but does so in three dimensions. [Caltech story]
