Dr. Timothy Ku is an aqueous and sedimentary geochemist who examines questions related to early diagenesis, freshwater and marine carbonate systems, and paleoenvironmental proxies.  Part of his work examines the implications of biogeochemical cycling of elements at or near the sediment-water as it relates to mineral dissolution, mineral precipitation, or the preservation of isotopic signals.  Other projects use sediments as archives of past water column conditions to reconstruct the environmental history of a water body or the surrounding land.  The work usually consists of field collection and laboratory measurments.

Dr. Timothy Ku grew up in Northeast Ohio before attending the University of Rochester and the University of Michigan.
