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]

Counting L.A.’s Trees

07-27-16

Professor Pietro Perona, has developed a method using Google Earth and Google Street View to count the trees in the city of Los Angeles. The process of counting the trees using human tree counters is very expensive and would cost about $3 million today. The last time the city did such counting was more than two decades ago and at the time there were 700,000 street trees. Perona has tested the methodology in a section of Pasadena where the city recently commissioned a sidewalk survey. By comparing the results to the known inventory, he determined that the computer was about 80% accurate. [LA Times story] [KPCC story]

122nd Commencement Ceremony

06-10-16

Caltech’s 122nd commencement ceremony was held on Friday June 10, 2016. The commencement speaker was surgeon, writer, and public health researcher Atul Gawande, MD, MPH. He reminded the graduates that, “today, you become part of the scientific community, arguably the most powerful collective enterprise in human history. In doing so, you also inherit a role in explaining it and helping it reclaim territory of trust at a time when that territory has been shrinking.” He also cautioned them and explained, “the mistake … is to believe that the educational credentials you get today give you any special authority on truth. What you have gained is far more important: an understanding of what real truth-seeking looks like. It is the effort not of a single person but of a group of people—the bigger the better—pursuing ideas with curiosity, inquisitiveness, openness, and discipline.” [The Mistrust of Science]

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 Vaidyanathan Receives Northrop Grumman Prize for Excellence in Teaching

06-08-16

P. P. Vaidyanathan, Professor of Electrical Engineering, is the recipient of the 2016 Northrop Grumman Prize for Excellence in Teaching. The Prize is awarded to an EAS professor who demonstrates, in the broadest sense, unusual ability, creativity, and innovation in undergraduate and graduate classroom or laboratory teaching. A nomination for Professor Vaidynathan read, “he has been an incredibly talented, dedicated, consistent, and responsible teacher throughout his career at Caltech. He is simply a great teacher who not only does a great job of conveying pertinent and important material to the students, but also spends the time to convey the thought process.” One of the students in his course stated, “this is one of the best-taught courses at Caltech. Period. That's especially nice since signals and systems are such important topics. He is a great professor and lecturer. His lectures are extremely well-organized, and you never leave a lecture not understanding the concepts he discussed.”
