Assistant Professor
Assistant Professor
T212 Mechanical Engineering

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