Welcome to the home page of the Losego Group in the School of Materials Science and Engineering at the Georgia Institute of Technology. The Losego group is a highly interdisciplinary research team at Georgia Tech exploring novel materials structures to advance fundamental materials physics for technologically relevant applications. Our research interests include understanding transport (electrical, thermal, mass) at organic-inorganic interfaces and using meso-/nano-structuring as a tool for enhancing functionality of materials. We contribute to a number of fields including: thermal sciences, plasmonics, electronic materials, nanoscience, & renewable energy technologies.
