I'm interested in episodic memory, which is the ability we have to encode and later remember the unique events from our lives. My research combines two non-invasive measures of brain activity – functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) – to provide an understanding of the neural processes that underlie this ability.

I'm particularly interested in addressing questions such as:

To what extent does retrieving a memory involve re-engaging in the thoughts, emotions, and perceptions that were associated with an event?

Why do we sometimes consciously remember the details surrounding an event, but other times feel as though the event is merely familiar?

What strategies can we use to increase the likelihood of retrieving a memory?

How do areas of the medial temporal lobe (such as hippocampus and parahippocampal cortex) contribute to different aspects of episodic memory?
