Luiz Gustavo Cançado is an Associated Professor at the Physics Department of the Federal University of Minas Gerais (UFMG), Brazil. He received the Ph.D. degree in 2006, at the same University, studying Raman spectroscopy of carbon nanostructures. He spent three years (2007–2009) at the Institute of Optics (University of Rochester), as a post-doctoral fellow in the Nano-optics group, and one year (2016) at CREOL, The College of Optics and Photonics (University of Central Florida), as a Visiting Professor in the Photonics Diagnostics of Random Media group. He is currently interested in near-field optics, with emphasis on tip-enhanced Raman spectroscopy applied to 2D materials. He also works on the metrology of mass-produced graphene.
