Biography
Head of the department of Civil, Environmental and Natural Resources Engineering. The department hosts more than 200 researchers and teachers, 175 PhD students, and is responsible for 20 education programs. My education background is within Mechanical Engineering. I got my PhD 1996 in Physical Environment Technology, and became Associate professor in Engineering Acoustics 2006. My current research is focused on ultrasound controlled cavitation for process intensification. I have a broad experience in the field of sound and vibration research, linked to sound quality, transfer path analysis, and optimization and control of resonant systems. I have been supervisor or assistant supervisor for 7 doctoral dissertations, and supervisor for 20 Master Thesis’s. I also have 5 years’ experience as senior expert consultant within automotive and process industry.
