Prof. Dr. Natalie Banerji


Natalie Banerji is currently a Full Professor of Chemistry at the University of Bern and leads the FemtoMat group. Her research interests include the study of organic and hybrid materials using ultrafast spectroscopic techniques, in view of solar cell and bioelectronic applications. She studied Chemistry at the University of Geneva and obtained her Ph.D. in Physical Chemistry in 2009, under the supervision of Prof. Eric Vauthey. She then moved to the University of California in Santa Barbara (USA), to work on organic solar cells during a post-doctoral stay with Nobel Laureate Prof. Alan J. Heeger (2009-2011). In 2011, she started her independent research career in Switzerland at the Ecole Polytechnique Férérale de Lausanne (EPFL) with an Ambizione Fellowship by the Swiss National Science Foundation (SNSF). She moved to the University of Fribourg in 2014, was subsequently nominated Associate Professor in 2015, and presided the Chemistry Department in Fribourg form 2016-2017. Click here for her full CV.
