Joel A. Tropp, Professor of Applied and Computational Mathematics, will receive the Compressive Sampling Pioneer Award at this year’s International Society for Optics and Photonics - Defense Security and Sensing conference (SPIE. DSS). He is one of the first researchers to contribute to the field of sparse approximation, which is also known as compressive sampling. At the conference he will give a presentation on sampling theorems for structured signals, based on his paper entitled “Living on the Edge.”
Katherine Faber, Simon Ramo Professor of Materials Science, has received one of the most prestigious awards given by the American Ceramic Society which is the John Jeppson Award. She is being honored “for her important engineering contribution to the understanding of mechanical behavior, especially toughening of ceramics.” More specifically for her study of the fracture of brittle materials and the mechanisms by which such materials can be toughened and strengthened through composite strategies and residual stresses.
Thomas H. Heaton, Professor of Engineering Seismology, and colleagues’ recent study suggests that all of our phones and other personal electronic devices could function as a distributed network, detecting any ground movements caused by a large earthquake, and, ultimately, giving people crucial seconds to prepare for a temblor. "Thirty years ago it took months to assemble a crude picture of the deformations from an earthquake. This new technology promises to provide a near-instantaneous picture with much greater resolution," says Professor Heaton. [Caltech story]
Louisa Avellar, graduauate student in Mechanical and Civil Engeineering, has received an NSF Graduate Research Fellowship. The awards support three years of graduate study within a five-year fellowship period in research-based master's or doctoral programs in science or engineering. [Caltech story]
To make an exact copy of an object with a 3-D printer, you must first produce a high-resolution scan of the object with a 3-D camera that measures its height, width, and depth. The most sensitive systems generally are too large and expensive to be used in consumer applications. Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, has created a new device called a nanophotonic coherent imager (NCI) that is an inexpensive silicon chip less than a millimeter. The NCI provides the highest depth-measurement accuracy of any such nanophotonic 3-D imaging device. 3-D imaging may be a possible feature in future smartphones. [Caltech story]
For one week at the end of March, 32 students from 20 universities and 14 countries came to Caltech for an intensive training experience in space mission design: the Caltech Space Challenge. The teams—Team Explorer and Team Voyager—were tasked with designing a manned mission to an asteroid placed in orbit around the moon. Aside from determining details such as the best type of vehicle to use, the optimal launch date, and how to keep the astronauts safe, each team was asked to explain how its mission would explore and make use of the asteroid to enable future missions to more distant locales, such as Mars. In the end, Team Voyager came out slightly ahead of Team Explorer. According to the jury, the deciding factor was Team Voyager's presentation and success in turning their technically detailed report into a compelling story for the audience.

Jonathan H. Liu, a senior undergraduate student working with Professor Sandra M. Troian, has received a Fulbright fellowship to conduct research in experimental biophysics at the Ludwig Maximilian University of Munich, in Germany. Specifically he will be studying the dynamics of DNA inside hydrodynamic systems subject to convective and thermophoretic forces.
Rob Anderson, a junior on the Caltech men's basketball team, has been named to the 2015 Allstate National Association of Basketball Coaches Good Works Team. Anderson, who is studying mechanical engineering and business economics and management, was selected for his extensive work researching and designing sustainable energy projects. "After the Solar Decathlon ended in autumn of 2013, I began looking for another engineering sustainability project," Anderson says. "I noticed there were a few empty gas-engine go-karts in Fleming and I realized I could re-engineer them to use electric power… That's basically how the Sustainable Vehicle Club was born.” [Caltech story]
Undergraduate mechanical engineering student Aaron Krupp has been awarded a Thomas B. Watson Fellowship to conduct a one-year purposeful, independent study outside the United States. Aaron’s project is entitled “the foundation of well-being: technology design to secure safety and necessity.” It will take him to India, Cambodia, Thailand, and Burma/Myanmar. He plans to investigate how technologies designed for function and accessibility can help break the cycle of poverty. [Learn more about the Fellows]
