Geochronology, cosmochronology, and isotope geochemistry. Formation and early evolution of the solar system. Early evolution of the Earth's crust and mantle. Precise calibration of the geological timescale. Decay constants, migration and partitioning of elements, natural and instrumental fractionation of isotopes, and other fundamental parameters and processes relevant to radiogenic isotope geochemistry. New techniques, applications, and instrumentation aimed at achieving the highest possible precision and accuracy in isotopic dating, isotopic analysis, and analytical geochemistry. Disequilibrium in U and Th decay series, and its application as a geochronometer and isotopic tracer. Quaternary geochronology. Radiation effects in solids.
