The Big Picture

12-03-18

Thanks to Professor Pietro Perona and his graduate students including Grant Van Horn and Sara Beery, the next wildlife photo you snap might set you on a path to helping map life on Earth. “The whole web, this huge repository of wonderful information, is indexed by words,” Perona says. “But when we have an image—a visual query—we don’t know what to do unless there is an expert next to us. We’ve gotten so numb to the idea that we’ll never find the answer out.” [Breakthrough story]

EE Alumnus on Forbes 30 Under 30 List

11-27-18

Fei Chen (BS ’11 EE) is on the 2019 Forbes 30 Under 30 list for “building better microscopy technologies … that could help explain how complex tissues like the brain, made of a large collection of diverse cell types, are organized.” As an Electrical Engineering undergraduate student at Caltech Fei Chen was an Axline Merit Scholar for his outstanding record of personal and academic accomplishments. Currently he is a Principal Investigator at the Broad Institute, Harvard-MIT. [Forbes 30 Under 30 Full List]

Spinning the Light: The World's Smallest Optical Gyroscope

10-25-18

Professor Ali Hajimiri and colleagues have developed a new optical gyroscope that is 500 times smaller than the current state-of-the-art device, yet they can detect phase shifts that are 30 times smaller than those systems. Their device achieves this improved performance by using a new technique called "reciprocal sensitivity enhancement." In this case, "reciprocal" means that it affects both beams of the light inside the gyroscope in the same way. [Caltech story]

Illuminating New Possibilities

10-10-18

Alireza Marandi, Assistant Professor of Electrical Engineering, explores how nonlinear photonics, a field of optics, enables a broad range of previously less-explored opportunities for using lasers and light detectors for a variety of purposes, including molecular sensing and computing. One possible application of his work is in breath analysis. He describes, “ there's a lot of useful information about your health contained in your breath, but it is difficult to analyze because the concentrations are so low. To overcome that, you could analyze the spectra of exhaled breath using lasers, searching for the spectral "fingerprints," or signatures, that reveal the presence of those compounds.” [Interview with Professor Marandi]

Caltech Awarded Federal Funding for Quantum Research

09-25-18

EAS Professors were among a small group of Caltech scientists and engineering who have won federal grants for research in quantum computing, and quantum networks. Professor Nadj-Perge (lead PI) along with co-PIs Professors Marco Bernardi and Andrei Faraon as well as co-investigator Professor Julia Greer have received funding for the program ”Quantum States in Layered Heterostructures Controlled by Electrostatic Fields and Strain," which is administered within the U.S. Department of Energy's Basic Energy Sciences division. Professor Austin Minnich is a co-PI of the program, "Quantum simulation of materials and molecules using quantum computation," which is part of the National Science Foundation's Research Advanced by Interdisciplinary Science and Engineering (RAISE)-Transformational Advances in Quantum Systems (TAQS) effort.

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]

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]

EE students Win $100K Qualcomm Innovation Fellowships

06-14-18

Graduate students Ehsan Abbasi and Fariborz Salehi, working with Professor Babak Hassibi, have won a 2018 Qualcomm Innovation Fellowship. They proposed a new algorithm for data recovery in Massive MIMO systems, which has a near optimal performance while being computationally efficient. Massive MIMO is the key enabler in the upcoming 5G data networks which promise considerably higher data rates in future generations of wireless networks. This year there were 174 submissions to Qualcomm for the fellowship and only 8 winning teams were chosen. Each winning team will be awarded a $100K fellowship and receive mentorship from Qualcomm engineers. [List of winners]
