Dr. Maria Vasilopoulou received her degree in Physics from the University of Athens and her PhD in Functional Materials for Nanolithography from the Chemical Engineering Department of the National Technical University of Athens. Then she worked, as a postdoctoral researcher, at the National Center for Scientific Research Demokritos (NCSRD) where she developed organic and inorganic materials for application as interfacial layers in organic solar cells and light emitting diodes. She is currently a senior Researcher at the Institute of Nanoscience and Nanotechnology of NCSRD. Her current activities are focused on perovskite solar cells and light emitting diodes as well as bioresorbable thin film transistors for brain activity recordings.
