Gift Enables Transformative Advances in Health Care


The Heritage Medical Research Institute (HMRI), a nonprofit founded by physician and Caltech trustee Richard Merkin, has extended its partnership with Caltech for a minimum of three more years. “I firmly believe that one person can change the world. Imagine what nine, focused HMRI investigators can do for understanding, diagnosing, and treating diseases,” says Merkin, who has served on the Caltech Board of Trustees since 2007. Caltech’s current HMRI investigators include EAS Professors Hyuck Choo, and Azita Emami. [Breakthrough story]

Engineered Metasurfaces Replace Adhesive Tape in Specialized Microscope


The latest advance in a new type of optics aimed at improving microscopy started with a game of tennis three years ago between Mooseok Jang a graduate of Professor Changhuei Yang's lab and Yu Horie working with Professor Andrei Faraon. "The hope is that our work will prompt further interest in this area of optics and make this type of microscopy and its advantages feasible for practical, everyday use—not just as a proof of concept," says Josh Brake, a graduate student in Yang's lab who continues to work on the project with Faraon and Yang.

New Process Allows 3-D Printing of Nanoscale Metal Structures


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 Wang Elected to the National Academy of Engineering


Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has been elected to the National Academy of Engineering (NAE). Professor Wang was elected for "inventions in photoacoustic microscopy enabling functional, metabolic, and molecular imaging in vivo." 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."

Engineers Create Stable Plasma Ring in Open Air


For the first time, Professor Morteza Gharib and colleagues have created a stable ring of plasma in open air using just a stream of water and a crystal plate. The team fired the water jet at surfaces of different textures and found that the smoother the surface, the clearer the structure of the plasma ring. The ring is stable, and as long as the water continues to flow, the ring maintains its shape and size. [Caltech story]

Laser-Imaging Technology Brought into Focus


Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and colleagues have improved a technique for taking three-dimensional (3-D) microscopic images of tissue, allowing them to see inside living creatures with greater precision than before. "This gives us the ability to look through opaque materials and see what's inside," Professor Wang says. "It's like an extension of the human eye, like Superman's X-ray vision."  [Caltech story]

The Science of Sweat


Wei Gao, Assistant Professor of Medical Engineering, is interested in the future of personalized and precision medicine, and is engineering the next generation of wearable health monitors and nanomachines that could enable rapid and hyper-localized drug delivery and surgery. The sweatband health tracker he is developing is capable of studying health at a molecular level. By analyzing an individual’s sweat, the device can monitor dehydration levels as well as blood glucose levels in real time. [Caltech interview]

New Microchip Technology Could Be Used to Track Smart Pills


Azita Emami, Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering; Investigator, Heritage Medical Research Institute; and EAS Division Deputy Chair, along with her colleagues including Professor Mikhail Shapiro have developed microscale devices that relay their location in the body. "We wanted to make this chip very small with low power consumption, and that comes with a lot of engineering challenges," says Professor Emami. "We had to carefully balance the size of the device with how much power it consumes and how well its location can be pinpointed." [Caltech story]

New App Replaces Ultrasound with Smartphone Camera to Measure Heart Health


Professor Morteza Gharib and colleagues including alumni Derek Rinderknecht (PhD '08), Niema Pahlevan (PhD '13), and Peyman Tavallali (PhD '14) and Caltech visitor in medical engineering Marianne Razavi have demonstrated that the camera on your smartphone can noninvasively provide detailed information about your heart's health. "In a surprisingly short period of time, we were able to move from invention to the collection of validating clinical data," says Professor Gharib. [Caltech story]
