Kelley Swanberg is a biomedical engineer with a specialization in magnetic resonance (MR), including magnetic resonance imaging (MRI) and especially in vivo proton magnetic resonance spectroscopy (1H MRS). During her career thus far Kelley has engaged in both methodological and applied investigations of MRI/S and its uses in both the lab and clinic, in addition to previous work in other subfields of preclinical and human neuroscience. Here Kelley is developing new ways to use magnetic resonance imaging and spectroscopy to investigate fluid flow through the glymphatic system in living bodies. Kelley’s favorite North American mammal is the opossum because they have the friendliest smiles and also the most teeth (50).
