Curriculum Vitae

       
Biography: The overarching goal of my research is to unmask the neural mechanisms that account for age-related changes in cognitive control processes and to translate these neuroscience findings into therapeutic interventions to alleviate these impairments. My desire to understand how our brains control our behavior started when I was an undergraduate at Denison University in Granville, Ohio. I soon became interested in learning about how neural systems could be disrupted by disease and degeneration in humans. These questions drew me to Suzanne Corkin's lab in the Department of Brain and Cognitive Sciences at MIT. In my doctoral dissertation, I studied how healthy aging affects brain anatomy and physiology and how these neural changes impact cognitive control processes. To pursue these questions, I took a multimodal neuroimaging approach, embracing structural MRI, DTI, fMRI, and MEG, and fostered collaborations in domains bridging clinical, systems, cognitive, and computational neuroscience. As a result, I showed that degeneration of white matter pathways disrupts top-down oscillatory activity, leading to impairments on tasks that engage prefrontal control networks. These studies furthered our understanding of how healthy aging affects cognitive control systems and provided new insight into the normal function of top-down and bottom-up attentional processes.

Research Description: While conducting my dissertation research, I became intrigued with the notion that deficits in attention processes could be treated using novel cognitive neurotherapeutic approaches. I am now pursuing this interest as a postdoctoral fellow in Adam Gazzaley's lab at UCSF. My current research objectives are 1) to unmask the neurophysiological mechanisms underlying rapid fluctuations of attention and top-down modulation, 2) to understand how these processes change with age, and 3) to assess the capacity for plasticity of attention by challenging the limits of information processing using adaptive, feedback-based cognitive training.
