Research synopsis

My research deals with human episodic memory, and I employ two non-invasive measures of brain activity - event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI) - to understand the cognitive and neural bases of this ability.

The different aspects of memory that currently hold my interest include:
            (1) the contributions of medial temporal structures to memory,
            (2) how encoding processes are reinstated during retrieval,
            (3) the strategies that influence memory retrieval, and
            (4) distinctions between recollection- and familarity-based memory.
