I have a position as Associate Professor (Docent) at the Division. I am a member of The Vibroacoustics Group. I conduct research in the fields of vehicle acoustics, tyre/road interaction modelling, mid- and high frequency methods, and active control of vibrations/smart materials, and I supervise PhD- and MSc-students and teach various courses in acoustics.
I was born and raised in Mariannelund in Småland, but lived also a year in Jönköping during my pre-university studies. Apart form acoustics, science and mathematics I am interested in novels, history, music and sports. I always enjoy listen to Meshuggah with high volume on the amplifier and I am a fanatic supporter of the icehockey team HV71 (Swedish champions 1995, 2004, 2008 and 2010).
In 1999 I got my Master of Science degree in “Civil Engineering, specialization Applied Mathematics directed towards Sound and Vibrations” at Chalmers. My MSc thesis was in the field of thermoacoustic refrigerators. I did a literature study and built a thermoacoustic device that uses sound waves to pump heat. 1998 I studied Theoretical Philosophy in a half-year course at Göteborg University, where I did the final work on Philosophy of Mathematics.
In 2000, I was enroled as PhD student at Applied Acoustics. In 2002, I got the Degree of Licentiate of Engineering (2.5 years of the total of 5 years for a PhD in Sweden). The title of the Lic. Eng. thesis was “High Frequency Tyre Vibrations”. In 2004, I was staying at Laboratoire Vibration Acoustique, INSA de Lyon, in Lyon, France, under the frame of an EC exchange programme.
In 2005 I got my PhD in Applied Acoustics, and the thesis has the title “Modelling Interfacial Details in Tyre/Road Contact – Adhesion Forces and Non-Linear Contact Stiffness”. I mainly studied how the very small length scale roughness of the road surface affects the interaction behaviour of the tyre/road contact.
In 2010, achieved the degree Docent in Applied Acoustics. My Docent lecture had the title “Challenges of Tomorrow in Vehicle Acoustics and Road Traffic Noise”.
