Ph.D., Stanford University Research Interests My research uses brain imaging (fMRI) in high-level cognitive tasks to study the neuroarchitecture of cognition. The fMRI studies examine how a network of brain areas activates during the performance of language comprehension, spatial thinking, problem-solving, and dual-task performance in complex environments. The empirical results are used interactively in the development of a computational architecture (called 4CAPS) that provides a mapping between cognitive function and brain activation. Models written in 4CAPS attempt to account for the behavioral performance (response times and accuracies) as well as the amounts and locations of the brain activations. I work with a large group of researchers of the Center for Cognitive Brain Imaging (where I am Co-Director) and collaborate extensively with biostatisticians at Carnegie Mellon and with researchers at UPMC.
