Dr. Audrey Geffen is a faculty member in the Department of Biological Sciences at the University of Bergen in Norway. She has worked on both fresh water and marine fish species in the USA (Wisconsin on Lake Michigan and Maine), and mainly marine species in the UK (Scotland and Isle of Man), Norway, and a few other places. She first started working with flatfish (plaice & turbot) during her PhD, and much of her research since has focussed on this group of fish. Dr. Geffen is often either combining or moving between aquaculture and ecology questions, and between a focus on early life history and population characteristics. The central theme in many of these studies has been a range of otolith analyses. Otoliths contain a lot of information which can be unlocked to answer a range of physiological, biological and ecological questions and thus provide temporal and spatial perspectives on individuals and populations. In 2018 Dr. Geffen took a 4-year break from full-time research to delve into reforms in university teaching, as a strategic teaching fellow at Imperial College in London. She says 'it has been challenging to experience the industrial side of university education. However, I am keeping my fins in the water with a few long-term projects and some talented research students. And even after all these years I still do not wear any otolith jewelry.'
