Research Interests:
In general, I am interested in human memory
function and spatial cognition. Additionally, I am interested in the behavioral
effects of stress hormones on these cognitive processes, as well as the
physiological effects of stress hormones on the various brain regions that
underlie these functions. My research focuses on the hippocampus, a region of
the brain that has been shown to be critical for episodic memory and spatial
navigation. Other regions of interest are the amygdala, an area of the brain
shown to be important for processing of emotional information, and the
parahippocampal gyrus, shown to be involved in spatial memory. My research
endeavors currently extend between two laboratories at the
In the Cognition and Neuroimaging Lab, I work in
collaboration with advisors, Dr. Lynn Nadel and Dr. Lee Ryan, to examine
hippocampal activation in humans, measured by functional magnetic resonance
imaging (fMRI), during retrieval of various types of information. My research
in this lab is particularly focused on examining hippocampal functioning during
retrieval of episodic memory under normal environmental and physiological
conditions. Currently, we are investigating the functional role of the
hippocampus, parahippocampal gyrus, and frontal lobes during retrieval of
spatial and nonspatial information, from episodic and semantic memory.
In the Anxiety Research Group, I work in
collaboration with faculty member Dr. Jake Jacobs, fellow graduate student Eric
Jackson, and post-doc Jessica Payne (currently at
