Biography

Reed earned his BSE in Material Science Engineering at Arizona State University in 2013. He then went on to complete a PhD in Energy Science and Engineering through the Bredesen Center, an interdisciplinary degree program centered on all aspects of energy, at the University Tennessee and Oak Ridge National Lab. His PhD dissertation focused on using materials and electrochemical methods to understand the fundamental processes at the Zinc (Zn) electrode of alkaline Zn batteries. After joining Sandia National Lab in 2019, he shifted focus to understanding fundamental aspects of safety and reliability of Lithium (Li)-ion and aqueous batteries. His current work includes materials and electrochemical characterization of Li-ion battery degradation mechanisms during long-term cycling, and fundamental origins of gas evolution in aqueous flow batteries.
