Gerd Grau is an Associate Professor in the Department of Electrical Engineering & Computer Science at York University. He received his BA and MEng degrees in Electrical Engineering from the University of Cambridge in 2011 and his PhD from the University of California, Berkeley in 2016. His research interests lie in additive manufacturing processes, especially printed electronics and 3D printing, that enable the deployment of microelectronics in new ways. Gerd’s lab works on all aspects of these novel microfabrication processes including printing physics and fluid mechanics, the development of new printing tools and techniques and the integration of various electronic and structural materials to fabricate devices for applications such as biomedical systems.
