Biography

Dr. Washton is the capability lead for NMR and EPR, and provides scientific and technical expertise and leadership in support of EMSL’s user program, strategy and scientific productivity. Washton works on coupling NMR with computational chemistry and bioinformatics to provide users with an integrated system for identifying unknowns and making predictions of NMR parameters and species based on computational and simulation data.

Washton specializes in solid-state nuclear magnetic resonance (ssNMR) and studies of surface reactivity in complex oxide systems and their interfaces. Applies ssNMR to study the reactivity of clays and aluminosilicate minerals (e.g., feldspars), natural and synthetic glass and fiberglass materials, and many metal oxide systems, including the interactions between metal oxides and organic matter in soils and atmospheric particles.
