Dr. Wallaschek is Director of the Institute of Dynamics and Vibration Research at Leibniz University Hannover, Germany. He has over 25 years of professional research experience in the field of mechatronics, dynamics and vibration in both academia and industry. His research is focussed on contact mechanics and friction, piezoelectric systems and ultrasonic engineering, and he has contributed to the continuous development of ultrasonic vibration motors. During his academic career Jörg Wallaschek has supervised more than 60 successfully completed PhD projects. He has authored more than 150 scientific publications, including contributed chapters on sensors and actuators, modelling of electromechanical systems, energy harvesting technologies, and textbooks on engineering mechanics. Jörg Wallaschek teaches courses on engineering mechanics and structural dynamics at Leibniz University Hannover, Germany and gives expert seminars on vibration technologies at Haus der Technik and VDI-Wissensforum. He is member of editorial boards of scientific journals (including Archive of Applied Mechanics and International Journal of Vibroengineering) and steering committees of international conferences. He serves as reviewer for public organisations and as consultant for small, medium and large enterprises. He is Fachkollegiat of the German National Research Council (DFG) in the expert panel on mechanics
