Harold H. Kung is professor of chemical and biological engineering at Northwestern University. He received his BS degree in chemical engineering from the University of Wisconsin, Madison, and his PhD degree in chemistry from Northwestern University. His main research interest has been in the area of heterogeneous catalysis. Recently, his interest broadened into synthesis of nanostructured materials, energy storage, global energy supply and consumption, and sustainability. He authored “Transition Metal Oxides: Surface Chemistry and Catalysis,” and is recipient of the P.H. Emmett Award and the Robert Burwell Lectureship Award (North American Catalysis Society), the Herman Pines Award (Chicago Catalysis Club), Catalysis Society of South Africa Eminent Visitor Award, and Cross-Canada Lectureship of the Catalysis Division of the Chemical Institute of Canada. He is a fellow of American Association for the Advancement of Science, and an editor of Applied Catalysis A: General since 1996.
