A team led by Nanfang Yu, assistant professor of applied physics, has discovered a new phase-transition optical material and demonstrated novel devices that dynamically control light over a much broader wavelength range and with larger modulation amplitude than what has currently been possible.
Six outstanding research efforts have been selected as finalists for this year's ACM Gordon Bell Prize in High Performance Computing. One of the finalists, titled “Extreme-Scale Phase Field Simulations of Coarsening Dynamics on the Sunway Taihulight Supercomputer,” involves the joint work of Qiang Du, the Fu Foundation Professor of Applied Mathematics in the APAM Department, along with his former postdoc (the lead author, currently a research scientist at the Chinese Academy of Sciences), his former student (currently a professor at the Univ. of South Carolina), and other collaborators in China.
Dan Bienstock, Mark Cane, Qiang Du, David Keyes, Kyle Mandli, and Chris Marianetti (co-chair) are part of the Data Science Institute’s newest working group —Frontiers in Computing Systems. The group will try to address some of the bottlenecks facing scientists working with massive data sets at Columbia and beyond. From astronomy and neuroscience, to civil engineering and genomics, major obstacles stand in the way of processing, analyzing and storing all this data.
Prof. Adam Sobel's' op-ed was recently published in The New York Times: "Climate scientists like me believe that human-induced climate change will strengthen hurricanes and lead to worse disasters. We know that significant global warming, over a degree and a half Fahrenheit, has already occurred since preindustrial days. So where, you might ask, are the powerful hurricanes? They’re coming, if we don’t take more aggressive action to slow climate change."
Irving Herman has been named the Edwin Howard Armstrong Professor of Applied Physics in the Fu Foundation School of Engineering and Applied Science. His appointment has been approved by the Trustees of Columbia University and he will be honored at the SEAS Faculty Excellence Celebration on September 20th, 2016.
