His work primarily investigates nest predation in forest birds like capercaillie and black grouse, analyzing interactions between mesopredators (pine marten and red fox). He employs snow tracking and camera surveillance methodologies across multiple Norwegian regions. Key research themes include:

• Predator competition dynamics
• Impact of landscape parameters on nesting success
• Evaluation of hand-reared gamebird releases
• Human land use effects on predator populations

Publications span 2010–2024, with recent studies focusing on capercaillie nest predation factors (2024), microtine rodent influence on pine marten populations (2024), and long-term comparative analyses across 16 countries (2016).
