David L. Shuster
Faculty Researcher & Geochronologist
My work is primarily focused on understanding processes that occur at and near the surfaces of Earth, Mars and Earth's moon. All of my work involves laboratory-based geochemical observations and the development of analytical techniques and numerical modeling tools for addressing specific questions. Because the application of "geochemical tools" requires a deep understanding of the basic physics and chemistry of geochemical systems --which in many cases is quite limited-- many of my recent efforts have involved basic research to quantify properties such as kinetics of diffusion and retention characteristics of radiogenic nuclides, and production rates of cosmogenic nuclides.
I am presently engaged in projects studying the development of topography in numerous glaciated and non-glaciated mountain landscapes across the globe, the development and BLANK
preservation of chemical weathering profiles, and the thermal conditions experienced by lunar samples and meteorites as related to impact events and paelomagnetic observations. Opportunities to become involved with these and other projects currently exist for prospective graduate students and postdocs.
