We have openings for Postdoctoral Researchers to conduct research on the development of integrated electrochemical systems for upgrading alternative feedstocks through conversion and reactive separations. You will actively participate in a multidisciplinary team performing materials and component design, catalyst and system benchmarking, advanced characterization, and modeling and simulations. These positions are in the Materials for Energy and Climate Security group within the Materials for Emerging Applications and Extreme Conditions section of the Materials Science Division in the Physical and Life Sciences Directorate. This position may offer a hybrid schedule, which includes the flexibility to work from home one or more days per week, after a probationary period. The specifics of the hybrid schedule, including the exact number of days required in the office and virtual work options may vary based on the needs of the team and the organization.  You will Conduct research in electrochemical system design, synthesis, and testing, including characterizing the reaction kinetics, materials physicochemical properties, and performance degradation. Develop systems for benchmarking catalysts and electrolyzers, and for in situ characterization of the dynamics of electrolyzer components and local reaction environments. Develop electrochemical reactors and components for reactive separations, critical materials separations, and/or nitrogen conversion. Contribute to and actively participate in the conception, design, and execution of experiments to establish design principles for catalysts and scale-up of electrolyzers. Collaborate with scientists in a multidisciplinary and multi-institution team environment to accomplish research goals. Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory. Maintain laboratory protocols, equipment, and best safety practices. Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences. Perform other duties as assigned.
