Professor Clarkson was awarded a B.A. in Chemistry with honors from Hamilton College in 1965, and a M.A. and Ph.D. in chemistry from Princeton University in 1969. He has been on the faculty of the University of Illinois since 1982, before which he served on the chemistry faculty at the University of Wisconsin (Milwaukee) and was the head of the EPR division of Varian Associates (Palo Alto). He uses magnetic resonance methods (NMR, EPR, ENDOR, ESE, DNP, and field-cycling relaxometry) to characterize the molecular structure of disordered materials, including species adsorbed at the gas-solid interface, and to study biologically important systems. He has received NSF and PRF Fellowships, and is currently the Co-Director of the Illinois EPR Research Center. Special research interests in addition to those already mentioned include developing methods of bioanalytical EPR, techniques for functional MRI, and the development and characterization of MRI diagnostic pharmaceuticals.
