My research interests relate to the organization of episodic memory in the human brain. As part of the discipline of cognitive neuroscience, my research addresses the relationship between the cognitive and neural processes that allow humans to remember their past. It builds upon diverse methodological approaches, such as the investigation of memory impairments in neurological patients, cognitive experiments in healthy individuals, the examination of brain activity with functional neuroimaging techniques (fMRI), and brain stimulation with transcranial magnetic stimulation (TMS). Some of the specific questions addressed concern how memory systems interact with the visual system when we recognize something we say earlier, whether different parts of the brian support memory for different types of information, and how memory processes contribute to the detection of novelty in the environment.

Our lab’s general research interests pertains to the functional and neuroanatomical organization of episodic memory in the human brain. As part of the discipline of cognitive neuroscience, this research addresses the relationship between the cognitive and neural processes that allow humans to remember the past. Our research builds upon diverse methodological approaches: the investigation of memory impairments in neurological patients, cognitive experiments in healthy individuals, the examination of brain activity with functional neuroimaging techniques (fMRI), and brain stimulation with transcranial magnetic stimulation (TMS).  Questions addressed by our lab include how memory systems interact with the visual system, whether different parts of the brain support memory for different types of information, and how memory processes contribute to the detection of novelty in the environment.
