RESEARCH
Overview
Prior to coming to Imperial College London, I held joint appointments as a researcher in the Demersal Fish Research Group at the Institute for Marine Research, and a professor in the Department of Biological Sciences, University of Bergen - in Norway. Much of my research on the growth and formation of fish otoliths concerns the application of otolith microchemistry to study fish ecology, stock discrimination, reproductive biology and individual life history. My work also demonstrates how combined analysis can be used to reconstruct the effects of climate on fish growth from historical samples.
My publications range from climate change studies, to fish age and growth, to aquaculture to plankton community studies, and my work with otoliths spans a wide range of species and life history stages. My research on fish otoliths as recorders of life history and life-long exposure to contaminants has led to many relevant international collaborative projects over the years. In addition to my research activities, she has been active in scientific publishing, serving on the editorial board and as editor of several journals. I am also on the steering committee of the International Symposia on Fish Otolith Research and Applications, receiving a life-time achievement award in 2018.
