I am an evolutionary ecologist with a strong interest in global change ecology. My research has mainly focused on understanding how environmental changes, and particularly climate change, affect animals that live in seasonal environments. I also have an interest in sustainable use of marine resources and work on several topics relevant to the Sustainable Development Goals.
