Our lab seeks to better understand how episodic memory allows us to store experiences and social interactions, mentally travel back in time to reimagine prior events, and reminisce with others. Our research uses brain stimulation to test theories of how the human hippocampus interacts with a distributed network of cortical regions to support episodic memory, and how neural activity patterns (especially theta rhythms) may be functionally relevant to specific aspects of memory. We design memory paradigms, take advantage of the whole-brain spatial resolution of fMRI (in healthy adults), and use noninvasive brain stimulation to modulate the hippocampal memory network and causally test its role in supporting long-term memory processes.
