Research

My field of research is homogenization. Homogenization is the branch of mathematics where partial differential equations with rapidly oscillating coefficients are studied. Besides pure mathematical problems I have also worked with different applications, mostly within tribology, composite engineering and flow in porous media.

Current assignments at LTU

  • Head of the department of Mathematical sciences (mathematics, mathematical statistics and scientific computing)
  • Chair professor in mathematics

Research council funding

Main applicant for the following grants from the Swedish Research Council (VR)

  • An interdisciplinary study of rough surface fects in lubrication by homogenization techniques, No. 621-2005-3168.
  • An interdisciplinary study of multiscale problems in tribology by homogenization techniques, No. 621-2008-5186.
  • Development of mathematical models and homogenization theory with focus on multi-scale problems in tribology: An interdisciplinary study, 2013-4978.

I am also a partner in another six grants from VR.
