As a graduate student under the mentorship of Dr. René Marois, my research employs functional magnetic resonance imaging (fMRI) and behavioral research methods to investigate how limits in visual attention and working memory capacity constrain our conscious experience of this richly detailed world and also what brain regions are involved in defining these capacity-limited processes.The focus of my research is on developing a better understanding of the neural correlates of visual short-term memory (VSTM) capacity limits, and how they constrain our explicit experience of the visual world. While my initial work focused on localizing brain areas that index the content of VSTM storage (Todd & Marois, 2004, 2005), I am currently investigating how different brain regions respond to the amount of information being consolidated to VSTM, as well as the behavioral consequences of taxing VSTM consolidation.
