Curriculum Vitae

Born in Monza in 1961, he is full professor of Experimental Physics since 2016. After his Physics degree at the University of Milano (1986). He earned his PhD in Physics at the University of Pavia. He worked as research scientist at the University of Milano, then at the Department of Material Science of the University of Milano-Bicocca. He was local coordinator of national research projects (1998, 2000, 2002) and coordinator of the network Insulators within the National Committee of the Consorzio Nazionale Interuniversitario per la Struttura della Materia. For 12 years, since 1997, he was project-leader at the Hasylab synchrotron radiation laboratory of DESY (Hamburg), coordinating high priority experiments founded by the European Community on the excitation properties of amorphous and nanostructured matrices. In 2011 he was appointed Director of the P.D. Sarkisov International Laboratory for Glass-based Functional Materials at the Mendeleev University of Moscow. During his activity he investigated defect structures in silicon and zirconium oxides by means of paramagnetic resonance and optical spectroscopy, as well as exchange interactions in transition metal oxides. His activity is now focused on glass-based nanostructured functional materials. In these fields he has activated collaborations with the Optoelectronic Research Centre of Southampton, the University College London, the Los Alamos National Laboratory, and with industrial partners (Pirelli). He is co-inventor of four patents on optical materials and applied spectroscopy. He received research fellowships by ST Microelectronics, by Enichem and, in 2010, he was winner of an international competition of the Ministry of Science of the Russian Federation in the field of Materials Science. He collaborates as reviewer with journals of the Nature Publishing Group (Nature Commun.),  Wiley (Adv. Mater., Small), the American Physical Society (Phys. Rev. Lett.), the American Chemical Society (ACS Appl. Mater. Interfaces), the Royal Society of Chemistry (J. Mater. Chem.), and several other journals of materials science. For more than 25 years he has given institutional lectures in experimental physics at the University.


Since 1992 he has appointed to faculty courses in Physics, Laboratory of Physics II, Spectroscopy II, Physics of Dielectrics, Laboratory of Advanced Technologies, Physics of Crystals, for different degrees at the University of Milano and University of Milano-Bicocca (Degree in Materials Science, Master in Materials Science, Degree in Science and Technology of Precious Materials, Degree in Biosciences). At present he is responsible for the courses of Physics of Dielectrics for the Master in Materials Science and Physics for the degree in Biosciences. He is a member of the Council of the Doctorate in Materials Science and Nanotechnology. Since November 2013 He is appointed Dean of the Teaching Coordination Council of Materials Science degree and master.
