Stephen Gray received a B.Sc. degree in chemistry from Carleton University, Ottawa, in 1977 and a Ph.D. degree in chemistry from UC Berkeley in 1982.  After post-doctoral work at Oxford University (1982-84) and The University of Chicago (1984-86) he was an Assistant Professor in the Chemistry Department at Northern Illinois University before joining Argonne in 1990 as a staff scientist in the Chemistry Division.  He moved to the Theory and Modeling Group at Argonne’s Center for Nanoscale Materials in 2009. 

His research focuses on the classical electrodynamics and quantum dynamics  of light-matter interactions in nanostructured systems, including problems in quantum plasmonics, sensing and information. 

He is a Fellow of the American Physical Society and has over 250 publications with an h-index of 67.
