He holds a position as associate senior lecturer in environmental sciences at Stockholm Resilience Centre, with a particular focus on ecosystem-based management of the Baltic Sea. His research is focused on seabirds, food-web interactions, trophic cascades and ecosystem regime shifts, and governance of marine resources.

He is currently primarily involved in developing the human dimension of FORMAS funded BEAM and Regime shift projects, aimed at understanding social-ecological dynamics of the Baltic Sea.

Henrik is also contributing to the Nippon foundation funded global marine governance project Nereus, predicting the future oceans.

Henrik has a PhD in marine ecology from Stockholm University and his thesis work was mainly focused on the effects of fisheries and fish stock dynamics on marine birds, and interest he gained from Triangle Island field station in the North East Pacific. Seabirds can function as indicators of change and studies of seabird population parameters can communicate the multiple and interacting impacts human activities and natural variability have on marine ecosystems — see www.balticseabird.com for more information on seabird research in the Baltic Sea.

During 2009 and 2010, Henrik did a post-doc at Fisheries Centre, University of British Columbia, Canada, supervised by Professor Rashid Sumaila. This post-doc gave him the opportunity to engage in social science theory and methods, in a study of non-compliance in the Southern Ocean and the emergence of international cooperation.

Henrik is using his experiences from the natural and social sciences to develop an integrated social-ecological research agenda for the "governance of coastal and marine systems" research theme, focusing on governance systems dynamics as well as social-ecological feedbacks and regime shifts.

Henrik is subject editor for Ecology and Society and member of the Swedish Council for Biological Diversity, a council that functions as a link between the scientific community and policy makers, primarily in relation to the Convention on Biological Diversity.

He is also board member for the Marine Science Centre at Stockholm University and represents Stockholm University in the advisory council for the Swedish Marine Institute.
