Ph.D. candidate - Paleoclimate, tectonics, and landscape evolution

How have mountain ranges, and the climates they are bathed in, changed through time? I study terrestrial paleoenvironments to discover what they have to tell us about paleoclimate and paleotopography. In order to tease out their histories and the feedback mechanisms at work, I primarily use geochemistry of light stable isotopes from sediments, soils, and organic molecules, in a context of data from sedimentology, structural geology, and other disciplines.
