Visiting Scholars

Ilaria Fratelli

Ilaria Fratelli is an Assistant Professor at the Department of Physics and Astronomy at the University of Bologna. She graduated in 2017 at University of Bologna in Physics after a brief internship at the University of Lisbon where she worked on the fabrication and characterization of flexible Thin Film Transistors based on high mobility amorphous oxides. She completed her PhD in Physics at the University of Bologna in 2021. During her PhD she spent 6 months at the CLUE lab where she worked on the fabrication of flexible Organic Field Effect Transistors by pneumatic nozzle printing. Her research mainly focuses on the investigation of novel printable semiconductors (e.g. organic small molecules, lead halide perovskites) to be employed as active layer in ionizing radiation detectors. Currently, she is a Marie Curie Postdoctoral Fellow and she will spend the outgoing phase (2024-2026) at Columbia University in the CLUE Lab. The main aim of the IDEATE project will be the realization and characterization of a wearable radiation detector based on organic and perovskite semiconductors to be employed for the real-time and in-situ monitoring of the dose of radiation absorbed by patients during radiotherapy treatments.
