The size of a fish determines much of its ecological role within the community, mainly through size-dependent life history events such as maturation and changes in dietary preferences. Therefore, factors acting on physiology and ecology that can drive change in the size of an individual and the size distribution of a population are important to study since they indirectly govern community dynamics.

I study how fishing and temperature changes growth of individuals and population structure and how this can affect species interactions and the evolution of life history traits in fish communities. I primarily use dynamic population model frameworks to study ecological and evolutionary responses to temperature in a community context to understand the trajectory of fish populations.

My PhD studies are funded by the Swedish research council Vetenskapsrådet and by the Department of Aquatic Resources at the Swedish University of Agricultural Sciences.
