Ryan J. Larsen is a Research Scientist with the Center for Nutrition, Learning, and Memory at the University of Illinois Urbana-Champaign. Dr. Larsen’s research uses MRI to study the physical correlates of cognitive performance, and how they relate to nutrition, cardiorespiratory fitness, and body composition. His research covers the human lifespan, including infants, children, young adults, and older adults. Dr. Larsen ’s research has employed a variety of techniques, including MR Spectroscopy, sodium MRI, relaxation parameter mapping, simultaneous EEG-fMRI, Arterial Spin Labeling, Diffusion Tensor Imaging, and Voxel-Based Morphometry. Dr. Larsen has also performed research on a variety of topics in materials science and mechanics, including rheology, stereology, materials synthesis, and the phase behavior of soft materials. Dr. Larsen holds a Ph.D. in Applied Physics from Harvard University.
