Professor, CEES


My research effort is mainly aimed at understanding life history variation in fish. Together with students and colleagues, I study why various populations of fish behave so differently and have so different life histories. I focus my research on traits that are important for fitness and population dynamics. I use a combination of methods such as classical field observations linked with field experiments, laboratory experiments, quantitative genetic studies as well as theoretical modeling exercises. Further, understanding individual variation is needed to better understand the dynamics of populations, and how such dynamics are influenced by factors such as climate (density independent factors) and various density dependent factors (competition, predation, harvesting).

My role in SUSTAIN

In SUSTAIN I will mainly be involved in the Mjøsa case study, with a focus on understanding the population dynamics of the brown trout population spawning in the Lågen river.
