Andrew joined the Chueh group in February 2016 after graduating from Drexel University with a PhD degree in materials science. Before PhD, he worked for 6 years on the oxide film growth in the lab of Andrey Kaul (Moscow State University) during his B.S. and M.S. With a deep expertise in thin film growth and characterization, he employs model single-crystalline surfaces for the fundamental studies of aqueous electrocatalysis and evolution of materials during electrochemical reactions. Combining atomically controlled growth of complex oxides, DFT and advanced in-situ electrochemical SPM, he designs artificial heterostructures and delves into the intricate relationship between the electrocatalytic activity and structural stability of perovskite oxides.
