Shaun Alia is a staff scientist in the Electrochemical Engineering and Materials Chemistry Group at NREL. He holds degrees in chemical engineering from the University of California, San Diego (bachelor's degree), the University of Connecticut (master's degree), and the University of California, Riverside (doctorate). He has worked in several areas related to electrochemical energy conversion and storage, including proton and anion exchange membrane-based electrolyzers and fuel cells, direct methanol fuel cells, capacitors, and batteries.

His current research involves understanding electrochemical and degradation processes, component development, and materials integration and optimization. Within HydroGEN, a part of the U.S. Department of Energy's Energy Materials Network, Alia has been involved in low-temperature electrolysis through NREL capabilities in materials development and ex- and in-situ characterization. He is further active within in-situ durability, diagnostics, and accelerated stress test development for H2@Scale and H2NEW. He has published approximately 45 peer-reviewed publications.
