My early enthusiasm for earth sciences was fed by a steady diet of outdoor activities and PBS documentaries. While it rapidly became clear that I would not be the next Jacques Cousteau, I found that I could combine my tastes for backpacking and physics as a geology/geophysics major. As a Harvard undergraduate, I constructed physical models of mountain-building processes between stints as a U.S. Forest Service ranger, then moved to Cambridge, England, where I conducted my Ph.D. research on magma migration in the mantle.
At Lamont, I have been extending magma migration theory into a more general one that describes the interactions between solids and fluids in the earth. Magma migration provides an important link between large-scale mantle convection and petrology/geochemistry and my research seeks to close the gap between these two disciplines. This work also lends new insights into other fluid-flow problems, current research is attempting to extend this theory to investigate dynamic fluid flow in sedimentary basins and groundwater hydrology. My work is primarily computational and my students, colleagues and I are implementing new techniques and technologies to take advantage of parallel computing. With a quantitative basis for fluid-flow research, we hope to integrate this theory with Lamont's strong observational programs in petrology, basin dynamics and groundwater tracer studies.
