Lecture notes

For the course Computational Physics (2009-2010) I rewrote previous lecture notes into six independent
lecture notes (see lecture notes 1-4 and 9-10).

Lecture notes on biomembrane physics for the course Living State Physics, Chalmers University (1999-2001).


Nine of my publications (Publications 30, 26, 24, 22, 17, 16, 13, 8 and 5) were selected for the Virtual Journal of Biological Physics, which highlights topical research.

Publication 15 was selected for the Virtual journal of Nanoscale Science and Technology.

Publication 30 was selected for the January 2011 issue of JCP: BioChemical Physics, which features biophysical content from Journal of Chemical Physics.

Publication 38 was selected IOP Select.
