Research
Underlying themes of my research are (1) the design and synthesis of novel transition metal complexes which exhibit new reactivity toward organic substrates, and (2) the study of organometallic complexes immobilized on a variety of support materials in an attempt to develop new types of "hybrid" catalysts which exhibit the combined properties of heterogeneous and homogeneous catalysts.
         

Current research projects include: the synthesis and reactivity of cluster complexes of cobalt, rhodium and iridium; the preparation of glassy carbon materials doped with different transition metal clusters; and the characterization of rhodium and iridium species bound to the surfaces of different oxide support materials. In addition to becoming familiar with the foundations of organometallic chemistry, members of my group become experienced in the manipulation and characterization of air sensitive materials and make extensive use of both solid and solution state NMR spectroscopies, extended x-ray absorption fine structure spectroscopy (EXAFS) and electrochemical methodologies.
