Popping Microbubbles Help Focus Light Inside the Body


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]

Cancer Treatment in a Painless Patch


Mechanical engineering undergraduate student, Teo Wilkening, spent this past summer working with Professor Gharib to test the preliminary design for an alternative—and possibly much less painful—method of chemotherapy drug delivery through a patch. To avoid the pain caused by the large needle traditionally used for such an intravenous injection, the team envisioned a patch containing hundreds of micrometer-scale needles, too small in diameter to be sensed by the nerves in the skin.

Professor Gharib Awarded the G.I. Taylor Medal


The Society of Engineering Science (SES) has selected Professor Morteza Gharib to receive the G.I. Taylor Medal. The award is made in recognition of Professor Gharib's sustained and outstanding research contributions to the area of fluid mechanics. Sir Geoffrey Ingram Taylor (G.I. Taylor) was a British physicist and mathematician, and a major figure in fluid dynamics and wave theory.

Norman Augustine Receives the 2015 International von Kármán Wings Award


Mr. Norman R. Augustine, Chief Executive Officer (Retired), Lockheed Martin Corporation is the 2015 recipients of the International von Kármán Wings Award. Mr. Augustine was recognized for his visionary leadership contributions to the aerospace industry and distinguished service to the nation's defense, security and space programs. Mr. Augustine has chaired both the 1990 Advisory Committee on the Future of the United States Space Program, and the 2009 Review of United States Human Space Flight Plans Committee. He has also served as the Under Secretary of the Army from 1975 to 1977 and in 1984 he published a series of aphorisms relating to engineering and business known as Augustine's laws. The von Kármán Wings Award acknowledges outstanding contributions by international innovators, leaders, and pioneers in aerospace and is presented by the Aerospace Historical Society, which is part of the Graduate Aerospace Laboratories at Caltech (GALCIT).

Digital Holographic Microscopy


Professor Morteza Gharib, and Dr. Jay Nadeau from GALCIT, as well as Dr. Christian Lindensmith from JPL are three of the four principle investigators on the holographic microscope project, dubbed SHAMU (Submersible Holographic Astrobiology Microscope with Ultraresolution). Their ultimate goal is to send the microscope on a spacecraft to search for biosignatures—signs of life—on other worlds such as Mars or Saturn's icy moon Enceladus. Holography is a method for recording holistic information about the light bouncing off a sample so that a 3-D image can be reconstructed at some later time. Compared to microscopy, holography offers the advantages of focusing over a relatively large volume and of capturing high-resolution images, without the trouble of moving parts that could break in extreme environments or during a launch or landing.

Toward a Smarter Grid


The power network of the future—also known as the smart grid—will have to be much more dynamic and responsive than the current electric grid, handling tremendous loads while incorporating intermittent energy production from renewable resources such as wind and solar, all while ensuring that when you or I flip a switch at home or work, the power still comes on without fail. An interdisciplinary group of engineers, economists, mathematicians, and computer scientists, including Professors Steven Low and Adam Wierman are working to develop the devices, systems, theories, and algorithms to help guide this historic transformation and make sure that it is properly managed.
