Research Interests
My research is driven by the desire to better understand cycling of elements and their isotopes between major geochemical reservoirs (continental crust, oceanic crust, seawater, the Earth's mantle) in order to understand the chemical evolution of Earth. Specifically, I am interested in how geochemical cycles have affected the (radiogenic) isotopic composition of seawater through time, and how to decipher those marine isotope records. My group has studied the effects of continental weathering, hydrothermal alteration of oceanic crust, accretion of extraterrestrial matter and, lately, anthropogenic and volcanogenic inputs on the geochemical cycling of radiogenic isotope systems (Re-Os, Rb-Sr, U-Th-Pb). Very recently, I have begun to explore the use of digital maps of bedrock geology in reconstructing geochemical cycles in the geologic past.
Education
After finishing high school in Osnabrueck, Germany, I studied Geology and Mineralogy at the Technical University of Clausthal, receiving my undergraduate degree in 1985. From there, I moved to the University of Goettingen, where I completed my Geology Diploma in 1989. After 15 months of Civil Service at the University Medical Center in Goettingen, I moved to Mainz to join Al Hofmann's Geochemistry Department at the Max-Planck Institute for Chemistry. During my PhD thesis, I spent three months as a guest student of Greg Ravizza in the Department of Geology and Geophysics at the Woods Hole Oceanographic Institution (WHOI). Following the completion of my PhD thesis in 1994, I returned to WHOI as a postdoctoral scholar, was appointed Assistant Scientist in the Department of Marine Chemistry and Geochemistry in 1996, Associate Scientist in 2000, and Tenured Associate Scientist in 2004.
