A study, headed by Rei Chemke, a Columbia Engineering postdoctoral research fellow, together with climate scientist Prof. Lorenzo Polvani, addresses a major discrepancy between climate models and reanalyses regarding potential strengthening or weakening of the Hadley circulation in the Northern Hemisphere as a consequence of anthropogenic emissions.
Dr. Amir Sagiv has joined the Applied Mathematics faculty. A main facet of his research is the study of random dynamics and time-reversal breaking in nonlinear optics. This work combines elements of both mathematical analysis and physical modelling, as well as extensive use of numerical simulations. The study and development of such simulations, and specifically numerical analysis of uncertainty-quantification (UQ) problems, is in itself a fascinating field in which computation, statistics, approximation, and transport theory all play a roll.
Chris Wiggins, Chief Data Scientist at The New York Times and Associate Professor of Applied Mathematics and Systems Biology, presented “Data Science at the New York Times” at Rev. He provided insights into how the Data Science group at The New York Times helped the newsroom and business be economically strong by developing and deploying ML solutions.
Kyle Mandli, assistant professor in applied physics and applied mathematics, was named to a new interdisciplinary program from the National Center for Atmospheric Research (NCAR). He is one of nine early career faculty members from U.S. universities chosen to work with NCAR scientists to investigate the impact of climate change and natural hazards on coastal areas with the goal of building greater societal resilience.
Simon Billinge, Professor of Materials Science and Applied Physics and Applied Mathematics, along with a team of scientists from UC Berkeley, Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory, Rensselaer Polytechnic Institute, and Brookhaven National Laboratory, have made important progress in understanding one of the most promising artificial photosynthesis catalysts, cobalt oxide. Their findings were published in PNAS.
