***I will NOT be considering PhD applicants for Fall 2023***

Research in the lab focuses on episodic memory and uses two non-invasive brain imaging techniques: functional magnetic resonance imaging (fMRI) and electroencephalography (EEG).

Research Interests

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 uses 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:

How does retrieving a memory involve re-engaging 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?

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