Visualization Brings Data to Life

10-28-16

Students participating in Caltech's Data Visualization program aim to tackle cumbersome data-manipulation problem such as how to drive a rover on Mars from a command room on Earth. One of the goals of the program is to develop innovative software to streamline the ways in which scientists and engineers visually manipulate their data. "We use a human-centered design methodology," Professor Mushkin says. "Design students create sketches and ask the researchers to 'interact' with them by pointing, talking, shuffling, and annotating the paper, while computer science students create rough drafts of a variety of possible approaches to coding the visualization."

Practical Mathematics: An Interview with Andrew Stuart

10-28-16

Professor Andrew Stuart is interested in how the current era of data acquisition interacts with centuries of human intellectual development of mathematical models that describe the world around us. His research is informed by—and has applications for—diverse arenas such as weather prediction, carbon sequestration, personalized medicine, and crowd forecasting. [Interview with Prof. Stuart]

Raising Temperature Changes an Element's Electronic "Topology"

10-27-16

Brent Fultz, Barbara and Stanley R. Rawn, Jr., Professor of Materials Science and Applied Physics, and colleagues have discovered a new way that heat tweaks the physical properties of a material. The potential value to engineers lies in the fact that it is much easier to raise the temperature of a material than it is to place it under the sort of pressure needed to force an electronic topological transition.

Noise-Canceling Optics

10-10-16

Changhuei Yang, Professor of Electrical Engineering, Bioengineering, and Medical Engineering, and colleagues have created the visual analogue of noise-canceling headphones—a camera system that can obtain images of objects obscured by murky media, such as fog or clouds, by canceling out the glare. Their device selectively cancels the scattered light, leaving only the light that is reflected or bounced off the objects and has slipped back through the murk unmolested. [Caltech story]

Your Future is Calling

10-03-16

Professor Morteza Gharib was one of the speakers at a recent symposium celebrating the Caltech–City of Hope Biomedical Research Initiative which provides seed grants to accelerate the development of basic scientific research and its translation into biomedical applications. Professor Gharib’s presentation was focused on measuring the ejection fraction, the fraction of blood that is ejected from the heart with each heartbeat. The group has designed a small piece of hardware that can connect to an iPhone and calculate a patient's ejection fraction—for less than $8. The device, called Vivio, gives comparable results to a cardiac magnetic resonance imaging, the gold standard in the medical industry for measuring heart health. [Caltech story]

Mechanics of Materials Across Nano to Geological Time and Length Scales

09-29-16

A symposium was organized at Brown University on September 16-17, 2016 to celebrate the technical contributions of Professor Ares Rosakis on the occasion of his 60th birthday. The symposium was chaired by Professors Pradeep Guduru, Huajian Gao, and G. Ravichandran. It brought together distinguished engineers and scientists from multiple disciplines to discussion research frontiers relating to the mechanics of materials across nano to geological time and length scales.

Modular Space Telescope Could Be Assembled By Robot

09-28-16

Professor Sergio Pellegrino and colleagues including Professor Joel Burdick, are proposing a space observatory with a 100 meters diameter primary mirror. Their design calls for the use of more than 300 deployable truss modules that could be unfolded to form a scaffolding upon which a commensurate number of small mirror plates could be placed to create a large segmented mirror. In this concept, a spider-like, six-armed "hexbot" would assemble the trusswork and then crawl across the structure to build the mirror atop it. [Caltech story]

James J. Morgan Symposium

09-23-16

On Friday September 23rd, 2016 the Environmental Science and Engineering Department hosted a day-long tribute to James J. Morgan, Marvin L. Goldberger Professor of Environmental Engineering Science, Emeritus. The symposium featured a series of presentations by his former students and leaders in the field of aquatic chemistry. Professor Morgan’s teaching and research centered on aquatic chemistry; major themes comprised rates of abiotic manganese oxidation on particle surfaces and flocculation of natural water particles, and chemical speciation proved the key. He came to Caltech as Associate Professor of Environmental Health Engineering in 1965 and became the Goldberger Professor of Environmental Engineering Science in 1987. He has served Caltech in a variety of capacities including Academic Officer for Environmental Engineering Science, Dean of Students, Executive Officer for Environmental Engineering Science, Acting Dean of Graduate Studies, and Vice President for Student Affairs.

Professors Newman and Orphan Named MacArthur Fellows

09-21-16

Environmental Science and Engineering Professors Dianne Newman and Victoria Orphan have been selected as 2016 MacArthur Fellows. Professor Newman's research focuses on microbial stress responses, with an emphasis on mechanisms of energy generation and survival when oxygen is scarce. Professor Orphan studies the molecular microbial ecology of anaerobic communities with a particular focus on microorganisms that live in deep-ocean sediment beds and consume large quantities of methane released from seeps in the ocean floor.
