Professor Vaidyanathan Elected to the National Academy of Engineering

02-07-19

P. P. Vaidyanathan, Kiyo and Eiko Tomiyasu Professor of Electrical Engineering, has been elected to the National Academy of Engineering (NAE). Professor Vaidyanathan was elected for “contributions to digital filter bank theory and design.” 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."

Meet the 2018 Amazon Fellows

01-16-19

The Amazon Fellows program is the result of a partnership between Caltech and Amazon AWS around Machine Learning and Artificial Intelligence (AI). The 2018 Amazon fellows are Ehsan Abbasi, Gautam Goel, Jonathan Kenny, Palma London, and Xiaobin Xiong. Abbasi is interest in contributing to a deeper understanding of convex and non-convex learning methods in AI and is an Electrical Engineering graduate student working with Professor Babak Hassibi. Goel’s research interest is at the interface of the theory and practice of machine learning and is advised by Professor Adam Wierman. London is also working with Professor Wierman. She is developing efficient algorithms for solving extremely large optimization problems. The methods are applicable to distributed and parallel optimization. For example in a distributed data center setting, the algorithms are robust to unreliable data transfer between data centers and take into account privacy concerns. Kenny is a Computation & Neural Systems graduate student working with Professor Thanos Siapas on deep neural networks to identify and classify brain states. Xiong is a mechanical engineering graduate student who enjoys working on real physical robots, to make them walk, jump, and run in real life. He is advised by Professor Aaron Ames and their research is focused on robotic bipedal locomotion

As artificial intelligence becomes mainstream, who will guide it?

12-18-18

In a recent Techer interview Electrical Engineering alumna Fei-Fei Li (PhD ’05) explains, “As we see artificial intelligence impacting the real world, it’s no longer a niche computer science, technical field. Policymakers, business leaders, educators, social scientists—they all need to take part and guide the future of A.I.” [Check out the full interview]

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]

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]
