Lorenzo Pavesi is Professor of Experimental Physics at the University of Trento (Italy). Born the 21st of November 1961, he received his PhD in Physics in 1990 at the Ecole Polytechnique Federale of Lausanne (Switzerland). In 1990 he became Assistant Professor, an Associate Professor in 1999 and Full Professor in 2002 at the University of Trento. He leads the nanoscience laboratory and teaches several classes at the Science Faculty of the University of Trento. He founded the research activity in semiconductor optoelectronics at the University of Trento and started several laboratories of photoncis, growth and advanced treatment of materials. He is in charge of the professional master in NEMS-MEMS, coorganized between University and ITC. He has directed more than 10 PhD studens and more than 20 Master thesis students. His research activity concerned the optical properties of semiconductos, the properties of III-V semiconductors grown on novel index surfaces, hydrogen in semiconductors, impurity diffusion in GaAs, disorder in superalttices and photonic crystals. During the last years, he concentrated on Si-based optoelectronics where he looks for the convergence between photonics and electronics by using silicon nanostructures. He is interested in active photonics devices which can be integrated in silicon by using classical waveguides or novel waveguides such as those based on dynamical photonic crystals. His interests encompass also optical sensors and biosensors. In silicon photonics, he is one of the worldwide recognized experts, he organized several international conferences, workshops and schools and is a frequent invited speaker. He manages several research projects, both national and international. He is an author or co-author of more than 250 papers, author of several reviews, editor of 10 books, author of 2 book and holds five patents. He was in the editorial board of Journal of Nanoscience and Nanotechnologies, in the directive council of the LENS (Florence), in the Board of Delegates of E-MRS.
