Björn has contributed to the work on Planetary Boundaries, and continues to review and synthesise scientific knowledge on, in particular, climate, and energy. Björn is also a Research Associate at Stockholm Environment Institute.

He is a graduate student in Natural Resource Management at Stockholm University, and his PhD research is geared towards understanding social learning, adaptive governance, institutions, and resilience. Within this field his research explores how and to what extent key social processes facilitate policy learning and sound natural resource management.

His licentiate thesis explores and discusses how social learning and social memory leads to both institutional resilience in terms of an analytical property linked to inertia in institutions, on the one hand, and to desired socio-ecological resilience on the other.

He has undergraduate studies in physics, mathematical finance, and psychology before taking a MSc in Complex Adaptive Systems from the Chalmers University of Technology, Sweden, and a BSc in Psychology from Göteborg University, Sweden.
