I have a broad interest in ecology with an emphasis on the effects of global change and climate change on populations in particular. I would study any organism to answer specific scientific questions, although my recent activity has been focused on arthropods. Most of my work has been related to the Arctic and the dramatic climatic changes currently happening there. My tools are primarily statistical modelling of long-term data, but I also have experience with agent-based modelling of animal populations.
