Lucia Romano obtained her PhD in Physics in 2006 from the University of Catania (Italy). After completing a post-doc at the University of Florida (Gainesville, USA), she was an assistant professor and researcher within the Department of Physics of the University of Catania (Italy) between 2009 and 2022. In 2014, Lucia Romano joined the Paul Scherrer Institute and ETH Zurich in Switzerland as a senior scientist to develop new methods of gratings' fabrication for application in X-ray interferometric tomography. She has a background in materials science for several kinds of applications, from the fundamentals of semiconductors to nanotechnology, from microelectronics to environmental applications, and X-ray optics. Lucia Romano has a long experience in semiconductors applied research, ion beam modification of materials, materials characterization, microfabrication, clean room operation, and equipment. At the moment, Lucia Romano’s scientific research focuses on metal-assisted chemical etching as a method for fabricating high-aspect-ratio structures in silicon. In her research, Lucia Romano is addressing fundamental open questions about metal-assisted chemical etching in order to fully explore the range of applications and the limits of this processing.
