I am fascinated by intraspecific variation in movement. How do different movement strategies evolve, and what are the ecological consequences of this variation? How do individual differences in behaviour (i.e. animal personality) influence movement strategies in the wild? I work primarily with aquatic organisms e.g. partially migratory fish in the lakes of southern Sweden. I also have an interest in how animal groups move i.e. in the collective decisions of animals.
I am broadly interested in the question of why individuals of the same species vary in their behaviour and life-history. What ecological factors drive the differences we observe in nature, and why is variation between individuals maintained?
During my Ph.D I investigated the role of early experience in the phenotypic development of the guppy. I manipulated the early social and physical environment of juveniles and assessed how this affected their behaviour and morphology as adults.
At Lund University as part of the CAnMove project I investigated the causes and consequences of partial migration in roach, asking why certain individuals make the decision to migrate and others to stay.
