Sampath Kommandur

Postdoctoral Researcher-Mechanical Engineering

Orcid ID

Sampath joined the Building Energy Sciences Group as a postdoctoral researcher in 2019. His research focuses on thermal management in buildings, including directional thermal transport using thermal diodes/switches/rectifiers and thermal and material characterization.

Sampath has a diverse experimental skill set in thermal, electrical, and material characterization and microscale lithography and material deposition technologies. Prior to joining NREL, his research focused on thermal metrology including experimental studies of temperature-dependent thermal transport in polymers and nanostructures and gas sensing using thermal conductivity detection. Sampath received a grant from Amazon Catalyst at The Electrochemical Society to study active control of thermal transport in semiconductors. Sampath also previously worked as a postdoctoral researcher at the Georgia Institute of Technology working on ultra-high vacuum chemical vapor deposition growth of complex oxide nanowires.
