Simonpietro Agnello received his Ph.D. in Physics at the Department of Physics and Chemistry, University of Palermo, Italy, where he currently works as Associate Professor. His research in experimental physics focuses on spectroscopic characterization of materials, matter-radiation interaction processes, and thermal modification of materials. Prof. Agnello is an expert of spectroscopic techniques, namely electron paramagnetic resonance, optical absorption spectroscopy, Raman spectroscopy and time-resolved optical spectroscopy. He actively studies advanced materials, nanostructured silica materials, carbon-based materials, and 2D materials. He has published about 300 research articles in peer-reviewed journals and has achieved an h-index of 28.
