His early research focused on elucidating the properties of chemical bonds using
X-ray diffraction and
neutron diffraction. Attending the International Conference on Synthetic Metals in 1979 in
Helsingør, Denmark, where
Klaus Bechgaard and
Denis Jérome reported on the superconducting behavior of (TMTSF)2PF6, introduced him to superconductivity in organic
charge-transfer complexes. Upon returning to ANL, he built up a program in organic conductors and superconductors. He played a role in the development of
organic superconductors in the United States. Building his background in structural and inorganic chemistry, he proposed design approaches for inorganic anions in organic charge-transfer complexes, which contributed to the discovery of several organic superconductors, including κ-type BEDT-TTF salts, by his research group. == Selected publications ==
