Research interests

I started out doing lower Silurian stratigraphy in Norway. Following my chance discovery of in Oslo 1982, I moved to Williamstown in 1983. There I have continued doing research both independently on the Silurian of Norway and in cooperation with Markes. Through time I have written on paleoecology, taxonomy, sedimentology and tectonic evolution of the Oslo Region and postglacial Neoproterozoic sedimentology in Finnmark, Norway. Lately I have also branched out to the rest of the Baltic Region. I specialize in biostratigraphy and brachiopod taxonomy and have a few new taxa on my conscience. Together with Markes Johnson I have written mainly biostratigraphic papers from Estonia, Russia, Australia, and North America besides Norway.

Diversification of rocky shore biota through time

Being the tecnological adept part of our husband/wife team, I have taken care of Markes' bibliographic rocky shore data. The changes of rocky shore biota through time are fascinating. This fascination has led to cooperative research on the topic.
