Lab Overview
Our lab investigates materials degradation and critical materials recovery across diverse environments. Our research spans corrosion and degradation from ambient to extreme conditions, including high-temperature aqueous and ionic-liquid systems, as well as the selective extraction, separation, and recovery of rare-earth and other critical materials. We integrate electrochemical approaches with materials characterization, including localized measurements, microelectrodes, and in-situ/operando techniques, to better understand degradation and recovery mechanisms and develop sustainable materials technologies.
