Professor Julia R. Greer Named Director of the Kavli Nanoscience Institute

10-03-19

Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering, has been named the Fletcher Jones Foundation Director of the Kavli Nanoscience Institute (KNI). Greer replaces professors Oskar Painter and Nai-Chang Yeh, who served together as co-directors. "I am delighted to begin spearheading the wonderful enterprise of the KNI, humbly following the footsteps of my predecessors, professors Painter and Yeh. I have been a KNI member and on the board of directors since shortly after I arrived at Caltech," Greer says. [Caltech story]

New Polymer Heart Valve Implanted in First Patient

09-18-19

Professor Morteza Gharib, has designed a new generation of heart valves that are longer-lasting, cost less to manufacture, and are more biocompatible than options that are currently available to patients. One of the new valves has been implanted into a human for the first time. "This is among my proudest moments. Creating something with the potential to save and improve lives is one of the reasons I became an engineer," Gharib says. [Caltech release]

New Metamaterial Changes Shape in a Tunable Fashion

09-12-19

Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering, has developed a new type of architected metamaterial that has the ability to change shape in a tunable fashion. The material has potential applications in next-generation energy storage and bio-implantable micro-devices. [Caltech story]

A Promising Step in Returning Bipedal Mobility

08-19-19

Professors Aaron Ames and Joel Burdick have launched a new research initiative, RoAM (Robotic Assisted Mobility), aimed at restoring natural and stable locomotion to individuals with walking deficiencies that result from spinal cord injuries and strokes. RoAm unites robotic assistive devices—including exoskeletons and prostheses—with artificial intelligence (AI)-infused neurocontrol. "Bipedal walking is difficult to achieve in a stable fashion," says Professor Ames. "While crutches help users of the exoskeletons to stay upright, they undercut many of the health benefits that upright locomotion might otherwise provide. In addition, they do not allow users to do anything else with their hands while walking." [Caltech story]

Microrobots Activated by Laser Pulses Show Promise For Treating Tumors

07-24-19

MedE Professors Wei Gao and Lihong Wang are working on microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body. "These micromotors can penetrate the mucus of the digestive tract and stay there for a long time. This improves medicine delivery," Professor Gao says. "But because they're made of magnesium, they're biocompatible and biodegradable." [Caltech story]

Lasers Aim to Replace Scalpels in Cutting-Edge Biopsy Technique

05-16-19

Professor Lihong Wang and Postdoctoral Scholar Dr. Junhui Shi have developed a new imaging technique that uses pulses from two kinds of lasers to take pictures of microscopic biological structures. This new approach, called ultraviolet-localized mid-infrared photoacoustic microscopy, or ULM-PAM, develops images of the microscopic structures found in a piece of tissue by bombarding the sample with both infrared and ultraviolet laser light. "Because ultraviolet light and infrared have different properties, we had to find special mirrors and glass that could focus both," Dr. Shi says. "And because no camera exists that can see both, we had to develop ways to see if they were correctly focused." [Caltech story]

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]

Partners In Innovation

11-13-18

Ten years ago, Caltech and City of Hope forged a partnership that combined what each institute was best at—engineering and medicine, respectively—with the goal of developing new biomedical technologies. At this year’s partnership celebration two projects were highlighted one involving Professor Yu-Chong Tai’s work on tracking tumors and the other building on Professor Morteza Gharib’s device to measure heart health.

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]
