Dr. Weber’s research interests include:  advanced diagnostics and mathematical modeling of various electrochemical devices, including solar-fuel generators, redox flow batteries, and polymer-electrolyte fuel cells; and a strong interest in multiscale and multiphase modeling of transport phenomena in these devices, including optimization of their operation for both performance and durability.  In addition, he has significant interest in characterization and understanding of ion-conducting polymers, both as membranes and as thin-electrolyte films, using traditional and synchrotron-based techniques.

Dr. Weber’s research focuses on continuum-scale modeling of integrated JCAP devices including mesoscale modeling of transport phenomena through ion-conducting polymers.  His team uses modeling to guide experimental design of materials and test-bed architectures and elucidate governing and limiting phenomena such that they may be optimized.

Dr. Weber is the Thrust 4 Coordinator for Numerical Modeling, Test-Bed Prototyping, and Benchmarking.
