Jarrod Lewis-Peacock received his B.S. in Computer Engineering, M.S. in Computer Science, and finally his Ph.D. in Psychology from the University of Wisconsin-Madison, and was a postdoctoral fellow in the Department of Psychology and the Princeton Neuroscience Institute at Princeton University before coming to the University of Texas at Austin in 2013. His research in the field of Cognitive Neuroscience focuses on understanding how the processes of working memory and long-term memory interact with one another in the human brain, and on how people dynamically deploy these resources in the service of pursuing their goals.His research in the field of Cognitive Neuroscience focuses on understanding how the processes of working memory and long-term memory interact with one another in the human brain, and on how people dynamically deploy these resources in the service of pursuing their goals. His lab uses a combination of behavioral methods, functional neuroimaging, and computational approaches to address these questions. For example, his research melds brain imaging with machine learning techniques to “peek under the hood” and test psychological theories in powerful new ways. By analyzing distributed spatial and temporal patterns of functional magnetic resonance imaging (fMRI) data, it is possible read out moment-to-moment information trajectories in the brain and identify what a person is seeing, retrieving from memory, holding in mind, and even forgetting. His lab is currently working to expand this approach to incorporate real-time neurofeedback – that is, providing information about a person's brain activity while they are performing a task in the MRI scanner. This state of the art methodology will enable experiments to test whether people can be trained to improve their memory abilities, and in some instances, to strategically impair them (for example, to intentionally forget things), through timely feedback based on real-time measurements of brain function.
