NSF-funded project: Using fieldwork, petrology and geochemistry, we develop tracers of melting and melt percolation processes in continental and oceanic lithosphere. Lately, we have been investigating how ophiolitic peridotites record the path of fluids in supra-subduction environments.
Those who help with the project: Nobumichi Shimizu (WHOI, USA), Henry Dick (WHOI, USA), M. Kurz (WHOI, USA)
Using geochemistry and experimental petrology, we develop tracers to track mineralogical heterogeneties in the source of mantle-derived melts.

DOEI-funded project: Using experimental petrology and x-ray microtomography, we investigate the geometry of fluids in subducted slabs to quantify how much seawater gets trapped and recycled in the deep Earth.
Those who help with the project: Glenn Gaetani (WHOI, USA), Wenlu Zhu and Kevin Miller (U. of Maryland, USA)
Andrew W. Mellon award-funded project: Using rheology experiments and analytical development, we investigate the effect of deformation on partition coefficients.
Those who help with the project: Lars Hansen (U. of Oxford, UK), David Kohlstedt (U. of Minnesotta, USA)
Using natural peridotites and analytical development at the ion probe, we are developing tracers of water in nominally volatile free minerals.
