The Possibilities are Mote and Remote
08-17-18
Professor Azita Emami’s work in high-speed data communications has led to a breakthrough that could spare millions of people the need to prick themselves with needles. As she engineers a more connected world, she also is working to make it a healthier one. Professor Emami doesn’t draw a line between the different endeavors. “Electronic systems for cell phones and computers are very, very advanced,” she explains. “So why not take the knowledge we have gained developing those technologies and find ways to apply it toward solutions in medicine?” [Breakthrough story]

Dragonfly Larvae Inspire New Designs for Prosthetic Heart Valves
07-17-18
Professor Mory Gharib and postdoctoral researcher Chris Roh (MS '13, PhD '17) have studied the design and control of the jets that dragonfly larvae use to propel themselves to re-design health values. "The current heart valve design is a one-size-fits-all, where no patient-specific design is considered, and this causes many post-transplant complications," Dr. Roh says. "We believe that an intentionally off-centered opening of the heart valve to more closely match the patient's original blood flow will be an important design parameter that can be adjusted based on each patient's heart morphology."

Winners of the 2018 Demetriades - Tsafka - Kokkalis Prizes Announced
07-10-18
The student winners of the 2018 Demetriades - Tsafka - Kokkalis Prizes were announced at the end of this academic year. Claire Bedbrook, advised by Professors Frances H. Arnold and Viviana Gradinaru received the prize in Biotechnology. Her research is in engineering proteins capable of controlling and reading out neural activity to advance neuroscience research. Nicholas Dou, advised by Professor Austin Minnich received the prize in Nanotechnology. Nicholas focuses on developing and characterizing novel nano-architected materials that are exceptionally lightweight, mechanically resilient, and thermally insulating. Xiaoqi Ren, advised by Professor Adam Wierman received the prize in Environmentally Benign Renewable Energy Sources. Xiaoqi’s research is focused on optimization of today's large-scale data centers, including online scheduling, energy usage and sustainability, and new market mechanisms for electricity markets and data clouds. Daniel C. Bowden, advised by Professors Joann M. Stock and Victor Tsai has received the prize in Seismo-Engineering, Prediction, and Protection. Daniel has worked on a range of projects relating to the propagation of seismic waves in the Earth's crust. Colin Cook, advised by Professor Yu-Chong Tai has receive the prize in Entrepreneurship. Colin is working on a phototherapeutic contact lens to treat diabetic retinopathy, a leading cause of blindness.

Wireless Pressure-Sensing Eye Implant Could Help Prevent Blindness
06-28-18
Azita Emami, Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering and Executive Officer for Electrical Engineering, Yu-Chong Tai, Anna L. Rosen Professor of Electrical Engineering and Medical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering, and colleagues have developed a new pressure-sensing implant for the eye that could help prevent one of the leading causes of blindness. The implant could help glaucoma patients monitor their condition by wirelessly sending data about the eye to the patient or medical professionals. Patients at risk for glaucoma are required to make regular visits to an ophthalmologist to have their intraocular pressure (eye pressure) checked. The disadvantage is that patients are only able to measure pressure while visiting their doctor. With a wireless implant, a patient has access to their eye pressure data at any time, and continuous monitoring will allow intervention sooner if needed. [Caltech story]

Laser-sonic Scanner Aims to Replace Mammograms for Finding Breast Cancer
06-18-18
A laser-sonic scanner, which uses photoacoustic computed tomography (PACT) developed by Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, can find tumors in as little as 15 seconds by shining pulses of light into the breast. The laser-sonic scanner provides a safer way for finding breast cancer compared to mammogram technology. Mammograms expose patients to X-ray radiation and requires their breasts to be painfully pressed between plates. Many women avoid having their mammograms taken as often as they should because of the discomfort involved. PACT can provide a clear view of structures as small as a quarter of a millimeter at a depth of 4 centimeters. Mammograms cannot provide soft-tissue contrast with the level of detail in PACT images. The PACT scan is quick, and a clearer image can be developed. [Caltech story]

Glowing Contact Lens Could Prevent A Leading Cause of Blindness
04-23-18
Hundreds of millions of people suffer from diabetes worldwide, putting them at risk for a creeping blindness, or diabetic retinopathy. Existing treatments, though effective, are painful and invasive, involving lasers and injections into the eyeball. Graduate student, Colin Cook working in Professor Yu-Chong Tai’s laboratory has invented a contact lens that when worn during sleep interrupts the process that destroys cells of the retina. He hopes his contact lenses will offer a solution that patients will be more willing to try because the effort involved is minimal, as are the side effects. [Caltech story]

Third Place At TigerLaunch
04-18-18
MedE graduate student, Colin A Cook, has won third place at the 2017-2018 TigerLaunch Finals for his pitch on a phototherapy contact lens he has been developing with his advisor Professor Yu-Chong Tai. TigerLaunch is a national entrepreneurship competition, dedicated to building student founder networks. It is the largest student-run competition of its kind with events in Chicago, NYC, Paris, Seattle, and Princeton. It had over 300 applicants in 2017 and over $30,000 in prizes. Colin learned about the competition and was encouraged to apply while taking Professor Ken Pickar's class E/ME 103: Management of Technology. [ENGenious feature on Colin Cook]
