Prof. Luca Dal Negro

Luca Dal Negro received both the Laurea in physics, cum laude, in 1999 and the Ph.D. degree in semiconductor physics from the University of Trento, Italy, in 2003. After his Ph.D. in 2003 he joined MIT as a post-doctoral research associate. Since January 2006 he has been a faculty member in the Department of Electrical and Computer Engineering and in the Material Science Division at Boston University (BU). He is currently a Full Professor of Electrical and Computer Engineering and a member of the Photonics Center. He also holds a joint appointment in the Physics Department at Boston University. Prof. Dal Negro manages and conducts research projects on light scattering from aperiodic media, nano-optics and nanoplasmonics, silicon-based nanophotonics, and computational electromagnetics of complex structures. He has authored and coauthored more than 220 technical articles and received several Awards, including the College of Engineering Excellence in Research Award and the National Science Foundation (NSF) Career Award. In 2017 Prof. Dal Negro was elected Fellow of the Optical Society of America (OSA) for “his numerous contributions in the theoretical and experimental aspects of wave interaction with aperiodic nanostructures”
