Academic Interests

Conservation of archaeological organic materials with a focus on wood, research into the deterioration of alum-treated wood, climate in museums.

Teaching

I teach a wood technology course through the Conservation Studies at the University of Oslo.

Higher education and employment history

I have a bachelor degree in biochemistry from McGill University, Montreal, Canada (1989) and a Master degree in Object Conservation from Queen's University, Kingston, Canada (1993). I have a PhD (2015) on the deterioration and reconservation of alum-treated wood through the School of Conservation, Copenhagen, Denmark. Since 1995, I have worked as a conservator at the Museum of Cultural History, University of Oslo. In the Saving Oseberg project (2014-2020) I worked as a conservation researcher. I currently am researching chemical properties of archaeological wood and leather, in addition to investigating alternative consolidation materials to polyethylene glycol for archaeological wood.

Collaboration

I have long standing collaboration with Professor Maria Perla Colombini's research group 'Chemical Science for the Safeguard of Cultural Heritage', at the Department of Chemistry and Industrial Chemistry at the University of Pisa, and with Professor Stephen E. Harding's group at the School of Biosciences, University of Nottingham.
