My stay as a Martin Luther King Visiting Professor offered me an unanticipated opportunity to reflect on the dream as public relations and the dream as reality. I was challenged anew by the gap between the two.
Background
Kwadwo Osseo-Asare is a distinguished professor of metallurgy and energy and geo-environmental engineering at Pennsylvania State University. Osseo-Asare holds BS, MS and PhD degrees in materials science and engineering from the University of California, Berkeley.
Interests
Osseo-Asare’s research interests include aqueous processing, materials synthesis and processing, nanoparticle synthesis, purification and assembly, wet processing in semiconductor fabrication, chemical-mechanical polishing, surface cleaning, and finishing, hydrometallurgy, separation science and technology, environmental systems, applied aqueous chemistry, interfacial and colloidal phenomena, surfactant science, semiconductor electrochemistry, and thermodynamic modeling.
His work is noted for providing new conceptual frameworks and experimental approaches that have significantly advanced scientific understanding of ion and particle transfer, dissolution, and precipitation processes in hydrometallurgy, environmental systems, nanoparticle technology, and semiconductor manufacturing. In 1997, he received the James Douglas Gold Medal from the American Institute of Mining, Metallurgical, and Petroleum Engineers for “his contributions to the fundamental understanding of interfacial phenomena in leaching, solvent extraction, and particle synthesis.”
