Lorenzo Pavesi is Professor of Experimental Physics at the University of Trento (Italy). He leads the Nanoscience Laboratory (25 people), 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 photonics, growth and advanced treatment of materials. He is the president and founder of the IEEE italian chapter on Nanotechnology. He has directed more than 20 PhD students and more than 20 Master thesis students. His research activity concerned the optical properties of semiconductors. During the last years, he concentrated on Silicon based photonics 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 or biosensors and solar cells. In silicon photonics, he is one of the worldwide recognized experts, he organized several international conferences, workshops and schools and is a frequently invited speaker. He manages several research projects, both national and international. He is an author or co-author of more than 280 papers, author of several reviews, editor of more than 10 books, author of 2 books and holds six patents. He is in the editorial board of Research Letters in Physics and 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. In 2001 he was awarded the title of Cavaliere by the Italian President for scientific merit. In 2010 and 2011 he was elected distinguished speaker of the IEEE- Photonics society. He is fellow of IEEE, of SPIE and of the italian physical society. He holds an H-number of 57 according to the web of science.
