I’m interested in understanding why organisms respond to human-induced environmental changes the way they do, and what the consequences are for populations, communities and ecosystems. The research topics range from effects of eutrophication and climate change on fishes to the impact of light pollution on insects. In addition, I attempt to synthesise the field through reviews, both traditional and systematic, and build conceptual frameworks to generate predictions and guide empirical and theoretical work.

I received my PhD in 1998 from University of Turku, spent one post doc period at University of East Anglia and another at University of Bern. In 2002 I moved to the University of Helsinki, and after a brief period as associate professor at Uppsala University in 2006-2007, took up my present position at University of Helsinki.
