Our group in the Department of Earth and Planetary Science at UC Berkeley and Berkeley Geochronology Center is interested in geologic processes and phenomena that occur primarily at and near the surfaces of Earth, Earth's moon and Mars. We study the timescales of such phenomena using observations of radiogenic and cosmogenic nuclides measured in our labs.  The questions that we address span orders of magnitude in space and time, ranging from the development of mountain topography during the Pleistocene to processes leading to magnetic fields recorded in early solar system condensates.  Our research is ultimately motivated by outstanding questions and problems in earth and planetary science. Because observational tools are often not available to address these question and related phenomena that occurred over geologic timescales, much of our effort is focused on developing an understanding of the basic chemistry and physics of geochemical systems in order to develop new sets of observations.
