Biographical Sketch:

 

Peter T. Wolczanski obtained his B.S. in Chemistry at the Massachusetts Institute of Technology in 1976.  There he helped Prof. Mark S. Wrighton initiate studies on the photoelectrolysis of H₂O with TiO₂ and SrTiO₃ photoelectrodes.  Despite a mediocre GPA, his undergraduate research and some temperance led to matriculation at the California Institute of Technology, where he was a Fluor Fellow in Prof. John E. Bercaw's group.  Investigation of zirconium hydrides, and the reduction of CO and related molecules ensued, leading to his Ph.D. in 1981, and honors as a McKoy Award winner.  After a 2 month postdoctoral stint with Dr. William P. Schaefer at Caltech, designed to permit participation in one last backpacking trip, he became an Assistant Professor at Cornell University.  Professor Wolczanski's previous research interests included the synthesis and reactivity of early transition metal complexes with small molecules, such as dioxygen, carbon monoxide, and methane, and the generation of solid state and polymeric inorganics from molecular precursors.  The molecular studies continue with an emphasis on bond activations, but new interests in metal-metal bonding, the consequences of aggregation, and the influences of electronic states on chemical reactivity have cropped up.  An Alfred P. Sloan and American Academy of Arts & Sciences Fellow, he is currently the George W. & Grace L. Todd Professor of Chemistry at Cornell.  He married Elizabeth A. Wood in June of 1993, and lives with her, their son Alex, and daughter Grace in a wooded area, where they fight a never-ending battle against the evil forces of nature (i.e., deer & weeds).  Occasionally he escapes for a round of golf, an ordeal that is usually followed by an attack on his wine cellar in order revisit his score.
