His research interests include materials for energy and sustainable development (superconductors and thermoelectrics); fabrication and characterization of thin films of oxides, ceramics and metals; study of the effect of nanostructuration on the physical properties; thermal transport; and vortex matter. He is the author of more than 100 papers in international scientific journals and four book chapters, and has two patents and has contributed to hundreds of communications at international conferences. He edited five books for Springer, including this one. Dario Narducci obtained his Ph.D. in Chemistry at the University of Milan. From 1988 to 1990 he was Post-Doctoral Fellow at IBM T.J. Watson Research Center. In 1990 he re-joined the University of Milan as an Assistant Professor, moving in 1997 to the University of Milano Bicocca, where he became Associate Professor of Physical Chemistry in 2000. His research interests have focused on the physical chemistry of silicon and on the transport properties of disordered materials. Since 2008 Narducci has developed an intense research activity on thermoelectricity for microharvesting. Since 2010 he is the Chief Technical Officer of a start-up developing silicon-based thermoelectric generators. He is currently involved in the ERC NanoThermMA project and is coordinating a Marie Skłodowska-Curie Global Fellowship in collaboration with the MIT to develop hybrid photovoltaic-thermoelectric generators. He is currently the president of the Italian Thermoelectric Society and served as the treasurer of the European Thermoelectric Society. Author of more than one hundred publications, Narducci also wrote books on nanotechnology and on hybrid thermoelectric-photovoltaic solar harvesters, and filed fifteen patents as well.
