Research interests:

I am generally interesting in infant cognition. Until recently, I have primarily been interested in infants' understanding of the physical world and concept formation. In particular I have done experimentally based work on object individuation, that is, the ability to decide the number of distinct objects present in a given scenario.

The Center on Autobiographical Memory Research was launched on the 1st of January 2010. The center is financed by the Danish National Research Foundation, and lead by Prof. Dorthe Berntsen, and I work as a core member at the center. I the years to come I will mainly conduct experimentally based research on the development of event or episodic memory, that may be seen as pre-cursers for autobiographical memory proper in older children and adults. I am especially interested in issues related to event segmentation in infants, their ability to remember events (by means of deferred and elicited imitation), and the paradox of childhood amnesia.
