Microscopic Devices That Control Vibrations Could Allow Smaller Mobile Devices


Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed phononic devices that include parts that vibrate extremely fast, moving back and forth up to tens of millions of times per second. The devices were developed by creating silicon nitride drums that are just 90 nanometers thick. The drums are arranged into grids, with different grid patterns having different properties. Professor Daraio, along with former Caltech postdoctoral scholar Jinwoong Cha, have shown that arrays of these drums can act as tunable filters for signals of different frequencies and can act like one-way valves for high-frequency waves.

Caltech President’s 2018 End of Year Message


President Thomas F. Rosenbaum’s end of the year message to the Caltech community highlights the InSight spacecraft landing and the celebration of Frances Arnold’s 2018 Nobel Prize in Chemistry. He states, “these recent events … underscore the extraordinary technological acumen that is necessary to realize the implications of big ideas. The Institute is known throughout the world for its mastery of fundamental science, but it is the connection of these fundamental precepts to engineering innovation that sets Caltech apart.” [Read the full message]

Nailing It: Caltech Engineers Help Show That InSight Lander Probe Can Hammer Itself Into Martian Soil


Professor José Andrade’s research team including Postdoctoral researchers Ivan Vlahinic and Jason Marshall have helped the InSight Mars lander boldly go where no one has gone before: beneath the surface of Mars. InSight is equipped with two main instrument packages: a seismometer for studying how seismic waves (for example, from marsquakes and meteorite impacts) travel through the planet and a "mole" that will burrow into the ground, dragging a tether with temperature sensors behind it to measure how temperatures change with depth on the planet. These instruments will tell scientists about Mars's interior structure (similar to the way an ultrasound lets doctors "see" inside a human body) and also about the heat flow from the planet's interior. When designing the mole the engineers at JPL wanted to be certain that it would be capable of reaching the necessary depth, and so they called on Professor Andrade, an expert on the physics of granular materials. He was able to develop new computer models that helped the JPL team predict the mole's effectiveness in Martian soil. Unless the mole encounters an obstacle, Andrade is confident that it will be successful. [Caltech story]

Caltech Awarded Federal Funding for Quantum Research


EAS Professors were among a small group of Caltech scientists and engineering who have won federal grants for research in quantum computing, and quantum networks. Professor Nadj-Perge (lead PI) along with co-PIs Professors Marco Bernardi and Andrei Faraon as well as co-investigator Professor Julia Greer have received funding for the program ”Quantum States in Layered Heterostructures Controlled by Electrostatic Fields and Strain," which is administered within the U.S. Department of Energy's Basic Energy Sciences division. Professor Austin Minnich is a co-PI of the program, "Quantum simulation of materials and molecules using quantum computation," which is part of the National Science Foundation's Research Advanced by Interdisciplinary Science and Engineering (RAISE)-Transformational Advances in Quantum Systems (TAQS) effort.

President Rosenbaum Highlights Postdocs as "Unsung Heroes"


In a letter to the Caltech community during National Postdoc Appreciation Week, the Caltech President emphasizes the role this key group plays at the Institute. He stated, “Caltech's mission of world-leading research and education depends crucially on our postdoctoral scholars. Although their time at Caltech may be short, they quickly become vital parts of the Institute's intellectual fabric.” [President’s Letter] [EAS Postdoc Resource Page]

Professor Lapusta Receives GSC Mentoring Award


The Caltech Graduate Student Council (GSC) has selected Professor Nadia Lapusta as the recipient of the 2017-2018, GSC Mentoring Award. The GSC Teaching and Mentoring Awards recognize individuals “who have an extraordinary impact on Caltech graduate students through their roles as teachers and mentors.” Nominators described Professor Lapusta as being an excellent cheerleader who fosters her students' ties with the community. Despite leading a large group, she makes significant amounts of time for her students. One student said, "the path ahead always seems more optimistic after our meetings."

Richard B. Chapman Memorial Awards


Morgane Anne Marie Grivel advised by Professor Morteza Gharib, Kazuki Maeda advised by Professor Tim Colonius, and Jason Schlup advised by Professor Guillaume Blanquart are recipients of the 2018 Richard B. Chapman Memorial Award. Morgane's research focuses on using hydrophilic and hydrophobic regions to modify hydrodynamic flows. Jason's research utilized computational fluid dynamics to investigate the highly unstable combustion of hydrogen-air mixtures with a focus on accurate, cost-effective modeling techniques. Kazuki does research in multi-phase flow, computational fluid dynamics, and biomedical engineering. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
