Research

Research Interests:

Applications of multinuclear NMR spectroscopy and imaging in solution and in solid state samples at high field (14.1 T). ESR and ENDOR spectroscopy.

The spectroscopy utilizes two frequency dimensions as well as MAS/CP techniques. Stray-field (STRAFI) MRI is used for solids and porous media: polymers, ceramics, dental cements and soils, and ingressing liquids. Soils include rice paddy field and dark earth soils from archaeological sites in the Amazon basin. New work is c.w. and pulsed EDR and ENDOR spectra of soils.
