Background and activities
I am interested in mechanisms of materials degradation on the atomic and molecular scale, and how these affect macroscopic systems behaviour.
On the method side, the group uses lab-based in situ and operando spectroscopy to study electrochemical processes. We are particularly focused on using applied vibrational spectroscopy (IR, Raman, others) fo investigating structural changes at interfaces.
To get some idea of the research work in our group, check out our publications.
TMT4255/TMM4170 - Corrosion (and Corrosion Protection) (together with Roy Johnsen)
TMT4242 - Steel Offshore (together with Morten Karlsen)
TMT4253 - Electrochemical Process- and Energy Technology (together with Ivana Jevremovic and Geir Martin Haarberg)
MT8102 - Corrosion and Surface Technology
In addition, you can meet me in individual lectures elsewhere, e.g. about vibrational spectroscopy in TMT4166 - Experimental Materials Chemistry and Electrochemistry.
