Group Leader

Prof. Luca Dal Negro

Luca Dal Negro received both the Laurea in physics, summa 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 an Associate Professor and a member of the Photonics Center at BU. 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 170 technical articles and received several Awards, including the College of Engineering Excellence in Research Award and the National Science Foundation (NSF) Career Award.

Dr. Svetlana Boriskina

Current Position: Postdoctoral Associate, Mechanical Engineering, MIT

I joined the group as a Research Associate in January 2008. Previously I worked as a Research Fellow at the University of Nottingham (Nottingham, UK) and a Senior Research Scientists at V. Karazin Kharkov National University (Kharkov, Ukraine).

I received my MSc and PhD degrees from the School of Radiophysics of V. Karazin Kharkov National University with a PhD thesis entitled “Scattering of surface waves and beams by open waveguide discontinuities & reflectors”. My main research interests include: boundary integral equations methods in computational electromagnetics, nanophotonics and plasmonics; theory and design of dielectric and semiconductor microcavities; whispering gallery modes coupling in photonic molecules and coupled-resonator optical waveguides; optical fiber mode solvers; and most recently, light scattering and localization in periodic and aperiodic photonic crystals.

Dr. Salvatore Minissale

I received my MSc at the University of Catania, Italy in December 2003 and my PhD at the University of Amsterdam, the Netherlands in March 2009. I moved to Boston in March 2010, after one year postdoc at the Institute for photonic science (ICFO) in Barcelona, Spain. My main research interests involve non-linear techniques, ultrafast optical spectroscopies such as pump-probe experiments, optical gain measurements on plasmonic and semiconductor nanostructures, Z-scan and Second Harmonic Generation (SHG) techniques for Nonlinear optics of nanoplasmonic structures.

Dr. Emanuele F. Pecora

Current Position: Postdoctoral Associate, Standford University

Born in 1983, Emanuele F. Pecora received his master degree in Physics (summa cum laude) in 2006 and the PhD in Physics in 2010 defending the thesis "Growth, properties and processing of group IV semiconductor nanowires" at University of Catania, IT. He worked as PostDoc fellow at Matis labs (Catania, IT) and then he joined the group in March 2011. His main research interest include growth and characterization of group IV semiconductor nanowires, ion irradiation effects in silicon nanostructures, luminescence properties of silicon nanostructures, rare earth optical properties, dopant diffusion and clustering in crystalline and amorphous silicon. Now, his research activity involves gain measurements and ultrafast optical properties of nitrides in the UV region.
