Hansson Wahlberg's primary research focuses on social ontology and the philosophy of causation. His work examines how social entities exist and function, particularly exploring questions about collective intentionality, institutional reality, and the metaphysical status of social groups. In the philosophy of causation, he investigates concepts like causal powers, sparse vs. abundant causation, and how causal relations operate at the social level. His recent publications show a concentrated effort to develop a comprehensive theory of social ontology while integrating insights from physics with social ontology. His major research projects include 'Metaphysics and Collectivity' (ongoing), 'Causation in the Social Domain' (2016-2018), and participation in networks like the Nordic Network in Metaphysics, International Social Ontology Society, and European Network for the Philosophy of the Social Sciences.
