received his S.B. and S.M. degrees in chemistry from the Massachusetts Institute of Technology where he conducted research in high resolution laser spectroscopy in the laboratory of Robert Field. He did his doctoral training at the University of California at Berkeley using molecular beam techniques to study excited atom reactions with Yuan Lee, and received his Ph.D. in chemistry in 1986. That same year he joined the the AT&T Bell Laboratories in Murray Hill, New Jersey as a Postdoctoral Member of Technical Staff to work on semiconductor surface excitations and chemistry with Mark Cardillo, Head of the Chemical Physics Department. In 1988, he went to the IBM Almaden Research Center in San Jose, California as a Visiting Scientist with Donald Eigler conducting research in low temperature scanning tunneling microscopy. He participated in the first experiments in which atoms were moved under control of the STM tip which later led to the development of the atomic switch. He came to The Pennsylvania State University as an assistant professor in 1989, his research focuses on understanding the chemistry and physics of surfaces on the atomic scale. He has developed techniques to study the chemistry and motion of individual atoms and molecules on surfaces. He has also developed the first technique capable of getting atomically resolved chemical information on insulator surfaces -- the tunable AC scanning tunneling microscope. His honors include a National Science Foundation Presidential Young Investigator Award, the BFGoodrich Collegiate Inventors Award, an Alfred P. Sloan Foundation Fellowship, and the American Chemical Society Nobel Laureate Signature Award in Graduate Education. He is presently an AssociateProfessor of Chemistry.
