text: Gary M. Hieftje is an analytical chemist, Distinguished Professor, and the Robert & Marjorie Mann Chair of Chemistry at Indiana University in Bloomington, Indiana. Gary M. Hieftje received his A.B. degree at Hope College in Holland, Michigan in 1964, and his PhD from University of Illinois at Urbana–Champaign in 1969. In 1969, he started his career in teaching and research at Indiana University. Hieftje was named a Distinguished Professor in 1985, and entered emeritus status in 2018. As of 2018, Dr. Hieftje has been involved in over 600 publications.
  Research in the Hieftje Group mainly focuses on studying and improving the mechanisms and methods of atomic emission and absorption, fluorescence, and mass spectrometry. He also works to develop new methods of analysis for atoms, molecules, and biomolecules. His group even developed an online computer program to control their experiments. Some areas of interest to his research are: finding new applications of lasers, linear response theory, near-infrared correlation methods of analysis, time-resolved luminescence, and fiber-optic sensors.
  Professor Hieftje has authored many books. Perhaps, the most well-known is “Chemical Separations and Measurements - The Theory and Practice of Analytical Chemistry” with colleagues Dennis G. Peters and John M. Hayes published by Saunders in Philadelphia in 1974.
