As a graduate student in Professor Charles P. Slichter's research group at the University of Illinois, Dr. DeSoto published the results of his Nuclear Magnetic Resonance (NMR) experiments conducted in a novel class of organic superconductors with a quasi two-dimensional crystal structure in the Physical Review Letters. His research proved that the spin-lattice relaxation mechanism for these superconductors was dominated by motion of the fluxoids, or little lines of magnetic field, poking through the material.
Dr. DeSoto met his Laura when both were students at Wheaton. They married in 1993 and now have two children, Gabriella and Zachary. They both love to explore the outdoors- rock climbing, backpacking and mountain climbing are among their favorite recreational pursuits.

Dr. DeSoto's current research interest is in the area of using Nuclear Magnetic Resonance (NMR) to probe the physics and dynamics of hydrogen storage in a new class of materials called Metal Organic Frameworks (MOFs) which show promise as safe and economical method of transporting hydrogen gas for use in fuel cells in hydrogen-powered automobiles.
