Summary:

Current Research

Magnetic Resonance Imaging (MRI) is a noninvasive experimental technique which has found broad application in clinical medicine and is a maturing method for studies in engineering and physics. Our group uses instruments that allow MRI to be applied with a resolution of 10 um over 10 mm diameter samples. MRI applied on this scale requires more sample specific tailoring of the pulse sequences and is more often termed Magnetic Resonance Microscopy (MRM) to distinguish it from medical scale imaging.

Our work is concerned with furthering application of MRM methods in the study of transport phenomena and material characterization. We use pulsed gradient spin echo (PGSE) techniques to measure velocity and effective diffusion, e.g. dispersion. The ability to spatially resolve velocity and diffusion fields allows for transport visualization. Application of PGSE methods without spatial resolution provide the scale dependent statistics of motion over the entire sample, rendering it a powerful technique for studying anomalous transport phenomena. The research program seeks to both elucidate new transport phenomena in complex systems and develop MRM methods for new applications.
