The APAM Department is pleased to announce the appointments of four new faculty members: Alexander Gaeta (professor of Applied Physics and of Materials Science Engineering), Michal Lipson (professor of Electrical Engineering and Applied Physics), Vincent Quenneville-Bélair (Chu Assistant Professor of Applied Mathematics), and Yuan Yang (assistant professor of Materials Science and Engineering).
Michael I. Weinstein, professor of applied mathematics (SEAS) and professor of mathematics (GSAS), has been named a Simons Math+X investigator by the Simons Foundation. The 5-year $1.5 million award, renewable for an additional 5 years, is a program established by the foundation in 2014 to encourage novel collaborations between mathematics and other fields in science or engineering.
The research team led by Prof. Nanfang Yu, along with collaborators from Univ. of Zürich, Univ. of Washington and BNL, have reported new discoveries on how Saharan silver ants (Cataglyphis bombycina) stay cool in one of the hottest places on earth. The report listed two distinctive yet connected traits that allow these ants to not only efficiently reflect incoming solar radiation, but also to emit thermal radiation efficiently in the mid-infrared, which allows the ant keeping its body temperature cool. Their report was published online in Science magazine on June 18th.
Kyle Mandli, assistant professor of applied mathematics, is working to develop better mathematical representations and computer models of tsunamis and storm surge in order to predict their potential impact, help emergency managers make critical evacuation decisions, and evaluate the effectiveness of protection measures, such as levees. He examines the physics behind why these phenomena intensify in shallow water and applies advanced algorithms to quickly and accurately predict these events.
Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, and, in doing so, they have developed molecular diodes that perform 50 times better than all prior designs. Venkataraman’s group is the first to develop a single-molecule diode that may have real-world technological applications for nanoscale devices. Their paper, “Single-Molecule Diodes with High On-Off Ratios through Environmental Control,” was published May 25 in Nature Nanotechnology.
