Caltech Awarded Federal Funding for Quantum Research

09-25-18

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"

09-24-18

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]

New Process Allows 3-D Printing of Nanoscale Metal Structures

02-09-18

Professor Julia Greer and graduate student Andrey Vyatskikh have created complex nanoscale metal structures using 3-D printing. The process, once scaled up, could be used in a wide variety of applications and opens the door to the creation of a new class of materials with unusual properties that are based on their internal structure.

Professor Bernardi Receives NSF CAREER Award

01-04-18

Marco Bernardi, Assistant Professor of Applied Physics and Materials Science, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his 5-year project, “First-Principles Electron and Spin Dynamics in Materials with Spin-Orbit Coupling”. The CAREER program is NSF's most prestigious awards for junior faculty members. The level and 5-year duration of the awards are designed to enable awardees to develop careers as outstanding teacher-scholars. Awardees are chosen because they exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.

Grad Student Makes Ultra-Sensitive Measurement of Deformation

07-13-17

Xiaoyue Ni, a materials science graduate student working with Professor Julia Greer, has shown that metals undergo permanent deformation even prior to yielding—the threshold at which a material under strain becomes permanently deformed. "What Xiaoyue's data are showing is that from the first moment you start deforming it, the dislocations start being active," Greer says. Now that we know how to do this, we can probe a variety of different classes of materials. [Caltech story]

Professor Yariv Elected to National Academy of Inventors

12-13-16

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering , has been named fellow of the National Academy of Inventors (NAI). His research has focused on creating the mathematical tools and building blocks underpinning guided wave optics, the backbone of today's optoelectronic technologies. This endeavor led to the proposal and demonstration of the distributed feedback laser and started the field of optoelectronic integrated circuits. Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."

Winners of the 2016 Demetriades - Tsafka - Kokkalis Prizes Announced

06-09-16

The student winners of the 2016 Demetriades - Tsafka - Kokkalis Prizes were announced at a special dinner with the Demetriades - Tsafka – Kokkalis family. Rachel P. Galimidi received the prize in Biotechnology for her work with Professor Pamela Bjorkman aimed to further understand the mechanism of HIV evasion of the humoral immune response. Junle Jiang was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Nadia Lapusta which used probabilistic inversion tools to understand the deep-ocean trench generated tsunamis that occurred during the subduction-zone earthquakes in Japan and Chile. Yinglu Tang working with Dr. Jeff Snyder received the prize in Environmentally Benign Renewable Energy Sources for her work on thermoelectric skutterudites for mid-temperature applications such as automotive waste heat recovery. The second winner in this category was Changhong Zhao who worked with Professor Steven Low to study the control and optimization of modern electric power systems. The winner of the prize in Nanotechnology was Gustavo Rios whose research involves development of a modular, scalable, nanofabricated neural probe system for dense 3-D electrophysiology to study animal brains. Rio’s graduate advisor was Professor Thanos Siapas. The prize in Entrepreneurship was given to Anton A. Toutov who was advised by Professor Robert Grubbs. His research interests lie in using fundamental chemistry to development radically new, sustainable ways to make everyday chemical products and generate clean energy.
