Research

Associate professor in Engineering Acoustics. My research is linked to sound quality and optimisation and control of resonant systems. Special interest is methodology for specification of sound quality, transfer path analysis, sound intensity and ultra sound induced cavitation.

I have supervised 7 doctoral dissertations and 6 licentiate thesises.

Have been involved in under graduate education at LTU since 1992. Senior lecturer in Engineering Acoustics since 2000. Supervisor and examiner for 20 Master Thesises.
