Professional Summary

Research career focused on the chemistry of metals at the Earth’s surface, with prinicpal focus in recent years on Mn, Fe, Cu and Pb. Systems studied include Mn-Fe ore bodies, constructed wetlands treating mine drainage, slope stability problems, and corrosion scales in drinking water systems. Supervised 9 PhD and 24 MS students.

Education

PhD, Harvard University, 1972.

Research Interests

Our research group is studying the geochemical behavior of sulfur and metals in three settings: sediment-hosted ore deposits, acid mine drainage,and drinking water distribution systems. For sedimentary ores, we have worked on deposits of iron, manganese, gold, uranium, and copper. Current projects include S and Sr isotopic chemistry of the Red Dog deposit in Alaska and similar deposits in Cuba, C-S geochemistry of black shales hosting Cu mineralization in Zambia, and diagenetic evolution of Au-bearing Witwatersrand quartzites in South Africa. We also have an extensive program of research constructed wetlands used to remediate acid mine drainage. We recently completed an extensive survey of S isotope chemistry of constructed wetlands, and are working on the chemistry of anoxic drain fills. Finally, our research group, under a grant from the American Water Works Association Research Foundation is pursuing problems of Pb and Cu contamination of drinking water arising from dissolution of minerals coating the insides of distribution pipes and household plumbing.
