Mariana Bertoni joined ASU as an assistant professor in 2012. Prior to this, she held senior scientist positions at two emerging start-up firms in the photovoltaic industry (Integrated Photovoltaics, Inc. and 1366 Technologies, Inc.), after completing a postdoctoral fellowship at the Massachusetts Institute of Technology (2008-2010). Her previous postgraduate experience includes a Marie Curie postdoctoral fellowship at Creavis Technologies & Innovation in Germany and a visiting researcher appointment at the National Renewable Energy Laboratory. Mariana received her Ph.D. in Materials Science and Engineering in 2007 from Northwestern University for her work on earth abundant transparent conducting oxides, and a Diploma in Chemical Engineering in 2000 from the Instituto Tecnologico de Buenos Aires. Her research seeks an understanding of how intrinsic and extrinsic defects of semiconductor materials affect electrical and optical properties of solar cell devices and device strategies to engineer processing steps that will maximize performance.
