This past August (2013), at the EnvironMetal Isotopes (EMI)
Conference in Ascona, Switzerland, Jennifer Druhan (of ESD and Stanford)
was awarded the prize for best oral presentation (out of 30 such
presentations). Her talk was entitled “Calcium isotope fractionation in
groundwater: A coupled modeling approach to quantify δ44Ca enrichment
during calcite precipitation.” The work described in the talk—funded by
the DOE SFA Program and resulting from Druhan’s collaboration with
several ESD scientists (including Carl Steefel, Ken Williams, and Don
DePaolo)—was part of a longer paper recently published in Geochimica et
Cosmochimica Acta on modeling the fundamental processes governing the
growth of calcite.
The EMI Conference assembled international scientists (PhD students
and more senior researchers) to present and discuss the latest
scientific effort in stable metal isotope fractionation, using
theoretical, experimental, and field-based approaches—with a focus on
applications in environmental studies.
Congratulations, Jenny!
