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

Eshan Govil Receives 2018 Henry Ford II Scholar Award

05-25-18

Computation and neural systems student Eshan Govil, advised by Professor Thanos Siapas, is a recipient of the 2018 Henry Ford II Scholar Award. He is fascinated by how machines can parallel the human mind, and wants to explore the applications of neurobiological research and neuroengineering to develop smart machinery and brain-computer interfaces. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

Caltech Celebrates 30 Years of its Computation and Neural Systems Option

09-06-17

Computation and Neural Systems (CNS) at Caltech explores the relationship between the physical structure of a computational system and the dynamics of its operation, as well as the computational problems that it can efficiently solve. At the symposium Professor Pietro Perona told the audience, despite CNS's success, its faculty members never rest on their laurels; they regularly reevaluate whether to continue the option and how to evolve its scope to keep it intellectually vibrant. Professor Carver Mead remarked, “I think it's true that the fields we bring together in CNS really do synergize. The goals aren't so different. Because to build something you have to understand it. And if you understand it, you can build it. That's a saying that Dick Feynman got from me." [Caltech story]

Professor Siapas Named Vannevar Bush Faculty Fellow

03-29-17

Athanassios G. Siapas, Professor of Computation and Neural Systems, has been named by the Department of Defense (DoD) as a 2017 Vannevar Bush Faculty Fellow. “The fellowship program provides research awards to top-tier researchers from U.S. universities to conduct revolutionary “high risk, high pay-off” research of strategic importance to the Department of Defense,” said Mary J. Miller, acting assistant secretary of defense for research and engineering. Professor Siapas has been named a fellow in the area of cognitive neuroscience. His research focuses on the study of information processing across networks of neurons, with emphasis on the neuronal mechanisms that underlie learning and memory formation. [DoD release]

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 Siapas Receives NIH Pioneer Award

09-22-11

Thanos Siapas, Professor of Computation and Neural Systems, has received a National Institutes of Health (NIH) Pioneer Award.  He plans to use the award to develop neural probes for large-scale recordings of brain activity. "Brain functions such as perception, learning, and memory arise from the coordinated activation of billions of neurons distributed throughout the brain," Siapas says. "While we know a lot about the properties of individual neurons, much less is known about how assemblies of neurons interact to perform computations. Our goal is to develop large-scale, multielectrode arrays that will enable the monitoring of many neurons simultaneously across different brain areas. We hope that such arrays will expose new fundamental insights into brain activity, and will find application in the study of animal models of brain disorders." [Caltech Press Release]

Athanassios Siapas and Evgueniy Lubenov Reveal the Driving Factor in the Brain's Self-regulation

04-18-08

Using computer models of neuronal circuits and experiments on live rats, Athanassios Siapas, Assistant Professor of Computation and Neural Systems, and his postdoctoral researcher Evgueniy Lubenov are revealing the curious mechanism by which the brain spontaneously tips itself toward a state balanced between order and chaos. The driving factor in the brain's self-regulation, they say, is the timing of neural pulses. "Networks self-organize to an intermediate state, in between the two extremes," Siapas says.
