Our goal is to develop new materials for sustainable energy applications. We want to contribute to scientific breakthroughs and see my research transformed into commercial products. My field is functional thin film materials science: find relations between growth, (defect)structure and physical properties in relation to their application. At present we investigate metal hydride based hydrogen sensors, chemochromic windows and hydride-based solid state electrolytes. Within the MECS group, I am collaborating with Wilson Smith and Fokko Mulder on (photo-)electrochemical conversion processes. Electrochemical conversion processes are key to store large amounts of electricity for long periods of time. On a larger TU Delft scale this topic is coordinated by the Delft e-Refinery program.
