Winners of the 2021 New Horizons Award Announced

06-10-21

The student winners of the 2021 New Horizons Award were announced at the end of this academic year. Sara Beery was recognized for her passion, energy, and fearlessness to improve the CMS program by founding the Women in CMS group, organizing events and discussions on racism in academia, and advocating for the support structures that improve the educational experience for all CMS students. Abigail (Abby) Jiang was recognized for her commitment to enhance the campus environment through her leadership of the Caltech Asian Pacific Islander Desi American student association (APIDA+) and of PRISM, the Caltech LGBTQ+ association, and her advocacy for other campus diversity initiatives. Daniel Mukasa was recognized for his dedication and leadership of Black Scientists and Engineers of Caltech, which catalyzed campus engagement, reflection, and reform, and for his mentorship of undergraduates through the WAVE program. Alexander Choi, Leah Ginsburg, Marcus Lee and Victoria Lee, were recognized for their collective engagement and sustained dedication to improve the quality of life for MCE graduate students that culminated in the initiation of a seminar series, an option-wide climate survey, the appointment of a Diversity Liaison, the creation of a MCE community statement, and formation of www.deiinitiatives.caltech.edu, a campus-wide data base for DEI activities.

New EAS Division Chair Announced

04-15-21

Harry A. Atwater, the Howard Hughes Professor of Applied Physics and Materials Science and director of the Liquid Sunlight Alliance (LiSA), has been selected as the new chair of the Division of Engineering and Applied Science. On July 1, he will begin his five-year term, taking over the Otis Booth Leadership Chair from current division chair Guruswami (Ravi) Ravichandran, the John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering. After more than three decades at Caltech, Atwater says he's looking forward to the opportunity to serve the Institute in a new way. "I'm excited to be able to pay back or pay forward all of the investments that Caltech has made in me," he says. "I'm excited to try to do what I can to catalyze research initiatives that my colleagues are excited to lead, and to make the division as strong and distinctive as possible." [Caltech story]

Titanium Atom That Exists in Two Places at Once in Crystal to Blame for Unusual Phenomenon

12-07-20

Crystals are usually good at conducting heat. By definition, their atomic structure is highly organized, which allows atomic vibrations—heat—to flow through them as a wave. Austin Minnich, Professor of Mechanical Engineering and Applied Physics, has discovered why a perfect crystal is not good at conducting heat, although it seemingly should be. "We have found that quantum mechanical effects can play a huge role in setting the thermal transport properties of materials even under familiar conditions like room temperature," says Austin Minnich.

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]

A Pathway to Longer-Lasting Lithium Batteries

08-06-20

The energy density of batteries have been a major challenge for consumer electronics, electric vehicles, and renewable energy sources. Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute, has made a discovery that could lead to lithium-ion batteries that are both safer and more powerful. Findings provide guidance for how lithium-ion batteries, one of the most common kinds of rechargeable batteries, can safely hold up to 50 percent more energy. "Every power-requiring application would benefit from batteries with lithium instead of graphite anodes because they can power so much more," says Greer. "Lithium is lightweight, it doesn't occupy much space, and it's tremendously energy dense." [Caltech story]

Ishani A. Karmarkar Receives 2020 Henry Ford II Scholar Award

06-22-20

Applied and computational mathematics student Ishani A. Karmarkar is a recipient of the 2020 Henry Ford II Scholar Award. Ishani is interested in data science and numerical algorithms, as well as applications to physical problems. This summer, she will be working on a SURF project on graph-based semi-supervised learning algorithms with Bamdad Hosseini, Senior Postdoctoral Scholar Research Associate, and Andrew Stuart, Bren Professor of Computing and Mathematical Sciences. In the past, she has also worked on a fluid modelling project with Sandra Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and completed a summer internship at Facebook. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

Chengzhe Zhou Receives 2020 Richard B. Chapman Memorial Award

06-11-20

Chengzhe Zhou, a graduate student in Physics supervised by Sandra Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, is a recipient of the 2020 Richard B. Chapman Memorial Award. His doctorate research focuses on the development of novel theoretical and computational tools for quantifying the nonlinear evolution and control of moving liquid boundaries driven by external fields. He hopes his findings offer new and useful analytic tools for investigating emergent small-scale dynamic phenomena in strongly driven nonlinear systems. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.

Microstructures Self-Assemble into New Materials

03-03-20

A new process developed at Caltech makes it possible for the first time to manufacture large quantities of materials whose structure is designed at a nanometer scale—the size of DNA's double helix. Pioneered by Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute, "nanoarchitected materials" exhibit unusual, often surprising properties—for example, exceptionally lightweight ceramics that spring back to their original shape, like a sponge, after being compressed. Now, a team of engineers at Caltech and ETH Zurich have developed a material that is designed at the nanoscale but assembles itself—with no need for the precision laser assembly. "We couldn't 3-D print this much nanoarchitected material even in a month; instead we're able to grow it in a matter of hours," says Carlos M. Portela, Postdoctoral Scholar. "It is exciting to see our computationally designed optimal nanoscale architectures being realized experimentally in the lab," says Dennis M. Kochmann, Visiting Associate. [Caltech story]
