Scarcity in the Modern World

04-08-19

A new book, Scarcity in the Modern World, examines how concerns about the scarcity of environmental resources such as water, food, energy and materials have developed, and subsequently been managed, from the 18th to the 21st century. The book is co-edited by Dr. Neil Fromer, Professor John Brewer, and their colleagues from University of Chicago and University of London.  It brings together scholars from a variety of academic disciplines to provide an innovative multi-disciplinary perspective that corrects previous scholarship which has discussed scientific and cultural issues separately. Other Caltech contributors to the book include Professors David Rutledge and Jean-Laurent Rosenthal. [Learn more]

Laser Technology Helps Researchers Scrutinize Cancer Cells

04-01-19

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and colleagues are using photoacoustic microscopy (PAM) to improve on an existing technology for measuring the oxygen-consumption rate (OCR). This new method allows the researchers to determine how oxygenated a sample of blood is by "listening" to the sound it makes when illuminated by the laser. Professor Wang calls this single-cell metabolic photoacoustic microscopy, or SCM-PAM. [Caltech story]

Computer Scientists Create Reprogrammable Molecular Computing System

03-20-19

Erik Winfree, Professor of Computer Science, Computation and Neural Systems, and Bioengineering, and colleagues have designed DNA molecules that can carry out reprogrammable computations, for the first time creating so-called algorithmic self-assembly in which the same "hardware" can be configured to run different "software." Although DNA computers have the potential to perform more complex computations than the ones featured in the Nature paper, Professor Winfree cautions that one should not expect them to start replacing the standard silicon microchip computers. That is not the point of this research. "These are rudimentary computations, but they have the power to teach us more about how simple molecular processes like self-assembly can encode information and carry out algorithms. Biology is proof that chemistry is inherently information-based and can store information that can direct algorithmic behavior at the molecular level," he says. [Caltech story]

Best Paper Award

03-13-19

Professor Pietro Perona along with Caltech alumni David Hall and Steve Branson have won the 2018 U. V. Helava Best Paper Award from the ISPRS Journal of Photogrammetry and Remote Sensing. Their paper “From Google Maps to a fine-grained catalog of street trees” was selected for the award. The jury described the work in the paper as “innovative, and applicable for large areas of tree classification and inventories. The developed methodology would affect practices of urban tree management globally.” [Read the paper]

Electrical Engineering Student Selected for 2019 Knight-Hennessy Scholars Class

03-06-19

Kavya Sreedhar, a senior double majoring in electrical engineering and business, economics, and management, has been named to this year's class of Knight-Hennessy Scholars, a graduate-level scholarship program founded by Stanford University. The program aims to develop a community of future global leaders to address complex challenges through collaboration and innovation. Sreedhar will receive a scholarship providing full tuition, room and board, and a living stipend while she pursues a PhD in electrical engineering. Her graduate work will be focused on circuits and hardware research for machine learning and artificial intelligence applications. She is joined by 67 other students chosen from a pool of 4,424 applicants for the program's 2019 cohort. [Caltech story]

2019 Caltech Distinguished Alumni

03-01-19

Caltech has recognized alumnus William Dally (PhD ’86, Computer Science) with the Distinguished Alumni Award, the highest honor regularly bestowed by the Institute. Dally was recognized “for his significant contributions to the architecture of interconnection networks. He developed much of the technology found in modern interconnection networks including wormhole routing, virtual-channel flow control, global adaptive routing, modern network topology, deadlock analysis, performance analysis, fault-tolerance methods, and equalized high-speed signaling.” [Caltech story] [Distinguished Lecture at Caltech]

Professor Marandi Receives NSF CAREER Award

02-19-19

Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his project, "Quadratically Nonlinear Micro-Resonators: Enabling Next Generation Photonic Devices and Systems". 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.

Professor Vaidyanathan Elected to the National Academy of Engineering

02-07-19

P. P. Vaidyanathan, Kiyo and Eiko Tomiyasu Professor of Electrical Engineering, has been elected to the National Academy of Engineering (NAE). Professor Vaidyanathan was elected for “contributions to digital filter bank theory and design.” Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature," and to the "pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."

New Materials Exhibit Split Personality

02-01-19

Julia Greer, Professor of Materials Science, Mechanics and Medical Engineering, and colleagues have determined that the failure of architected materials—the point at which they break when compressed or stretched—can be described using classical continuum mechanics, which models the behavior of a material as a continuous mass rather than as individual (or "discrete") particles. This finding implies a duality to the nature of these materials—in that they can be thought of both as individual particles and also as a single collective. [Caltech story]
