RESEARCH INTERESTS
-  

I am interested in episodic memory and how the brain supports our ability to retrieve and recreate past moments of conscious experience. A more concrete way this broad interest manifests is in understanding the contributions of the posterior parietal cortex (PPC) and its distinct subregions (i.e., superior parietal lobule, intraparietal sulcus, supramarginal gyrus, and angular gyrus) to the retrieval of episodic memories. The PPC has been demonstrated to show reliable activation during the retrieval of episodic memories, however, lesions to this swath of cortex do not produce amnesia. This intriguing dissociation, in addition to the PPC being a critical junction point for many different cognitive processes, has been the catalyst for many theoretical frameworks regarding the contributions of PPC subregions to episodic memory retrieval. My research also probes the role of the default mode network and its subsystems (which include regions of the ventral PPC/angular gyrus) in episodic memory, and cognition more generally.
