I hold a PhD in Materials and an MSc in Chemistry. I am an expert in the synthesis of advanced ceramics and material processing for electrochemical devices such as Solid Oxide Fuel Cells, electrolyzers and oxygen separation membranes.
My current responsibilities include the development of novel architectures for fuel cell electrodes and electrolysers. I am also pioneering a combination of electroless and electrodeposition techniques to improve and tailor the anode performance and durability. I have developed a novel oxygen separation membrane with very low metal content and capable of separating high purity oxygen from air.
