Areas of Expertise

• Population- and individual-level responses to increasing predation
• Fitness consequences of behavioural and physiological variation under predation and climate forcing
• Genetic connectivity, gene flow, and diversity during population decline
• Causes and consequences of breeding dispersal, choice of overwintering area, and migration
• Strategies, evolution of animal personality
• Life-history evolution
• Social evolution

Research Projects

• Ongoing project: Hormonal and genetic adaptations to a changing environment: a longitudinal population study of eiders (funding: Swedish Cultural Foundation in Finland)

Special Methodologies & Techniques

• Stress physiology: radioimmunoassay of corticosterone and other hormones (prolactin, thyroid hormones)
• Genetics: reduced‑representation sequencing (RAD‑seq)
• Movement: geolocator tracking
• Morphology and tagging: field measures and colour rings for individual identification
