Toward a Smarter Grid

10-19-15

The power network of the future—also known as the smart grid—will have to be much more dynamic and responsive than the current electric grid, handling tremendous loads while incorporating intermittent energy production from renewable resources such as wind and solar, all while ensuring that when you or I flip a switch at home or work, the power still comes on without fail. An interdisciplinary group of engineers, economists, mathematicians, and computer scientists, including Professors Steven Low and Adam Wierman are working to develop the devices, systems, theories, and algorithms to help guide this historic transformation and make sure that it is properly managed.

Professor Umans Named Simons Investigator in Computer Science

05-21-15

Christopher Umans, Professor of Computer Science, has been named a Simons Investigator in Computer Science by the Simons Foundation’s Mathematics and Physical Sciences Division. The award honors and supports "outstanding scientists in their most productive years, when they are establishing creative new research directions, providing leadership to the field and effectively mentoring junior scientists." Professor Umans’ research centers on algorithms and complexity. He has made contributions to the understanding of randomness in computation, and algorithms for fundamental algebraic problems which includes developing a group-theoretic approach for matrix multiplication.

Professor Tropp Receives Pioneer Award

04-22-15

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.”

Converting Data Into Knowledge

11-17-14

Yisong Yue, Assistant Professor of Computing and Mathematical Sciences, has focused his research in machine learning. He explains, “machine learning is the study of how computers can take raw data or annotated data and convert that into knowledge and actionable items, ideally in a fully automated way—because it's one thing to just have a lot of data, but it's another thing to have knowledge that you can derive from that data.” [Interview with Professor Yue] [ENGenious article]

Variability Keeps The Body In Balance

09-22-14

By combining heart rate data from real athletes with a branch of mathematics called control theory, John Doyle, Jean-Lou Chameau Professor of Control and Dynamical Systems, Electrical Engineering, and Bioengineering and colleagues have devised a way to better understand the relationship between reduced heart rate variability (HRV) and health.

"A familiar related problem is in driving," Doyle says. "To get to a destination despite varying weather and traffic conditions, any driver—even a robotic one—will change factors such as acceleration, braking, steering, and wipers. If these factors suddenly became frozen and unchangeable while the car was still moving, it would be a nearly certain predictor that a crash was imminent. Similarly, loss of heart rate variability predicts some kind of malfunction or 'crash,' often before there are any other indications," he says. [Caltech Release] [Read the Paper]

Programmed to Fold: RNA Origami

08-20-14

Paul Rothemund, Senior Research Associate in Bioengineering, Computer Science, and Computation and Neural Systems, and colleagues have fabricated complicated shapes from DNA's close chemical cousin, RNA. "RNA origami is still in its infancy," says Rothemund. "Nevertheless, I believe that RNA origami, because of their potential to be manufactured by cells, and because of the extra functionality possible with RNA, will have at least as big an impact as DNA origami."
