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 and a visiting scientist appointment at the Massachusetts Institute of Technology (2010-2012). Her previous postgraduate experience includes a postdoctoral appointment at the Massachusetts Institute of Technology (2008-2010), a Marie Curie postdoctoral fellowship at Creavis Technologies & Innovation in Germany (2007-2008) and a visiting researcher appointment at the National Renewable Energy Laboratory. She has published over 35 research articles in peer-reviewed journals and presented more than 30 papers at scientific meetings. She serves in the Center for Nanoscale Materials proposal evaluation board at Argonne National Laboratory and is active in various committees and chairing positions at the IEEE photovoltaic specialists conferences.
