Avinash Agrawal Receives 2017 Henry Ford II Scholar Award

05-09-17

Electrical engineering student Avinash Agrawal, working with Professors Burdick and Low, is a recipient of the 2017 Henry Ford II Scholar Award. Avinash is aiming to produce robot visualizations and simulations for a spherical robot. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to the engineering student with the best academic record at the end of the third year of undergraduate study.

Professor Wennberg Elected to the National Academy of Sciences

05-02-17

Paul O. Wennberg, R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering, as been elected to the National Academy of Sciences in recognition of his distinguished and continuing achievements in original research. His work applies traditional physical chemistry techniques to study the mechanisms of chemical transformation in the earth's atmosphere and in the carbon cycle. This research has helped create the Total Carbon Column Observing Network, which measures the distribution of greenhouse gases across the globe. [Caltech release]

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]

Professor Rosakis Elected to the National Academy of Sciences

05-03-16

Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, has been elected to the National Academy of Sciences (NAS). His research interests span a wide spectrum of length and time scales and range from the mechanics of earthquake seismology, to the physical processes involved in the catastrophic failure of aerospace materials, to the reliability of micro-electronic and opto-electronic structures and devices. The National Academy of Sciences is a private organization of scientists and engineers dedicated to the furtherance of science and its use for the general welfare.[Caltech story] [List of NAS members]

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]

Weak Electrical Fields in the Brain Help Neurons Fire Together

02-03-11

Costas Anastassiou, a postdoctoral scholar working with Professor Christof Koch, and colleagues have found that coordinated behavior occurs in the brain whether or not neurons are actually connected via synapses.  To tease out the effects, Anastassiou and his colleagues, focused on strong but slowly oscillating fields, called local field potentials (LFP), that arise from neural circuits composed of just a few rat brain cells.  Measuring those fields and their effects required positioning a cluster of tiny electrodes within a volume equivalent to that of a single cell body—and at distances of less than 50 millionths of a meter from one another.

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.
