History
I was born in Kiruna, Sweden, 1967. I received the M.Sc degree in electrical engineering from Luleå University of Technology, Sweden in 2004. Since 2004 have I been a Ph.D. student at Dept. of Computer Science and Electrical Engineering.
Current research
My research interest is on developing a sensor for fiber characterization for the pulp and paper industry, using a combination of ultrasound, optical and photoacoustical measurement techniques.
