Research interests:

My field is evolutionary ecology, with particular attention to how seasonality shapes ecological processes and evolutionary adaptations. Central topics include: Life history theory, Phenology, Behavioral ecology, Population dynamics, Trophic interactions, Ecosystem connections & Ecological and evolutionary modelling.

You can visit the Seasonal Ecology Group for more information on the work I do together with students and collaborators. Publications and are also available there, at ResearchGate or Google Scholar

I am currently on a sabbatical leave at Stockholm University and their Department of Ecology, Environment and Plant Sciences (DEEP), and Department of Zoology.

I am in the steering group of bioCEED, a Centre of Excellence in Education, where I lead the work package on Efficient leadership of education, and coordinate a Forum for Educational Leadership in Biology.
