George is investigating the co-production of hydrogen, synthesis gas and ethylene through water-splitting, methane partial oxidation and ethane dehydrogenation, respectively, facilitated by the use of mixed ionic and electronic conducting perovskite materials. He conducts experiments to quantify the performance of materials and then uses the measurements to extract fundamental information about the material operation by developing state of the art electrochemical and thermochemical models. His numerical work includes the development of detailed surface reaction and material diffusion models as well as their coupling with Computational Fluid Dynamics (CFD) algorithms towards the design of high-performance membrane reactors.
George joined the RGD laboratory in September 2012 as a graduate student.
