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]

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.

Professor Hajimiri Elected to National Academy of Inventors

12-16-15

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering; Executive Officer for Electrical Engineering; Director, Information Science and Technology, has been named fellow of the National Academy of Inventors (NAI). His research covers broad areas within high-speed and high-frequency electronics- and photonics-integrated circuits. This year, the Hajimiri group synthesized a 3-D camera—called a nanophotonic coherent imager—that provides the highest depth-measurement accuracy (similar to resolution) of any such nanophotonic 3-D imaging device. 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."

Popping Microbubbles Help Focus Light Inside the Body

12-03-15

Changhuei Yang, Professor of Electrical Engineering, Bioengineering, and Medical Engineering, and his postdoctoral colleague Dr. Haowen Ruan have developed a novel technique called time-reversed ultrasound microbubble encoded (TRUME) that uses gas-filled microbubbles to focus light inside tissue. "Ultrasound and X-ray techniques can only detect cancer after it forms a mass," Yang says. "But with optical focusing, you could catch cancerous cells while they are undergoing biochemical changes but before they undergo morphological changes." [Caltech story]

Student Research in Biomedical Optics Wins First Place

07-02-15

Electrical Engineering postdoctoral scholar Dr. Haowen Ruan and graduate student Mooseok Jang, who work with Professor Changhuei Yang, have won first place for Best Student Poster Presentation at the Engineering Conferences International (ECI) series entitled “Advances in Optics in Biotechnology, Medicine and Surgery XIV.” Their winning poster demonstrated research in biomedical optics, specifically a novel technique that focuses light inside biological tissue by time-reversing the light encoded through popping of a microbubble. The technique has the potential to enable one to “see” through biological bodies with light.
