Matthias Scheffler, a of matter. The method is increasingly director of the Fritz Haber Institute in Berlin used in industry, such as in research and and professor at UC Santa Barbara, is among development of pharmaceuticals, chemicals the leaders of the basic science effort to use and catalysts, and diverse engineering computational materials science to solve industries. “We can not only calculate equations that could lead to novel materials existing materials, but also make predictions discovery. Through his involvement with the about completely unknown materials, Institute for Pure and Applied Mathematics their stability and their properties, which (IPAM), Scheffler is building momentum may become experimentally and even for the endeavor by bringing together commercially useful,” Scheffler says. “The colleagues from around the world. number of so far unexplored materials is practically infinite. Thus, there is no doubt Density Functional Theory (DFT) dates that in the next years scientists will identify back more than a half-century to work new materials with novel property profiles by Walter Kohn, together with Pierre that could open new opportunities in fields Hohenberg and Lu Sham, that would later such as energy, mobility, safety, information, Matthias Scheffler earn him a Nobel Prize (shared with John and health.” Fritz Haber Institute (continued on page 7) INGRID DAUBECHIES GIVES GREEN FAMILY LECTURES IPAM’s 2016 Green Family Lecture Series, used to determine whether a painting is an held in May, featured Ingrid Daubechies, original, or whether or not two parts of a James B.
