Assistant Professor
Assistant Professor
T212 Mechanical Engineering

My multidisciplinary team is interested on energy storage concepts and how they are part of large energy systems. We find new innovations for conversion of electrical, thermal and chemical energy to each other and to store them efficiently and in sustainable manner. Our main focus is on hydrogen and power to X as an energy vectors, heat storage solutions and materials, energy recovery from batteries prior recycling and design of circular energy devices.
