Gary M. Hieftje

The field termed metallomics is in desperate need of new tools that offer simultaneous information about the elemental and species composition of complex samples.  Two such tools will be described and evaluated.  One uses a glow discharge to examine, on a simultaneous basis, protein-containing spots separated by a two-dimensional gel system.  With this device, metals associated with each protein can be determined, and the protein-metal stoichiometry deduced.  The second device employs a novel dual-source mass spectrometer to obtain, again simultaneously, information about the metals that a protein might contain and about the protein itself.

Professor Hieftje received an A.B. degree from Hope College, Holland, MI, in 1964 and a Ph.D. from the University of Illinois in 1969. He then joined the faculty at Indiana University as an assistant professor of chemistry. He became a full professor in 1977 and was named a Distinguished Professor in 1985. He is the author of over 500 scientific publications, 10 books, and holds 15 patents. Over 60 students have received doctorates under undergraduates and visiting scientists have performed research in his laboratories.
