Brian LeRoy

Professor of Physics

Director of Graduate Studies

Classification: Primary Faculty

Education: Ph.D., 2003, Harvard University

Fields of Study: Condensed Matter Physics

Research Interests: 

The LeRoy group studies low-dimensional materials using a combination of scanning probe microscopy and optical spectroscopy techniques. Current materials of interest are carbon nanotubes, graphene and transition metal dichalcogenides. These materials are studied using low-temperature scanning tunneling microscopy, atomic force microscopy and Raman spectroscopy.

Honors and Awards:
