The structure of episodic memory
When transforming naturalistic experience to memory, what is the basic unit of experience we encode? Do we save each moment as it is encountered? Or do we aggregate information in a temporary buffer, saving an entire event (meaningful chunk of experience) to long-term memory when the event is over? In complementary lines of research, we investigate whether the same structure is reflected in the storage and retrieval of event memory.

The boundaries of memory
A large body of research has demonstrated that people naturally segment continuous experience to events, at points in time defined as event boundaries. These event boundaries are a key organizing principle of perception and memory, driving changes in brain activity, behavior, and the organization of long-term memory. We study which features of experience are necessary/sufficient to form a boundary, and how boundaries at different levels of hierarchy modulate memory encoding.
Temporal dissociation of mnemonic processes
We previously found that the activity in several MTL (medial temporal lobe) regions can be divided into distinct temporal components, elicited by the onset, the duration, or the offset of a complex event. These temporal components are likely to reflect different aspects of mnemonic processing. In the posterior hippocampus, for example, when viewing familiar events (movie clips), the onset component was linked to familiarity while the offset component was linked to encoding. We are interested in characterizing the role of the different components more broadly, across regions in the MTL, and in a range of tasks.
