Research Topics

My personal research interests have sought to bring together a number of interrelated disciplines within Earth and environmental sciences. These are linked by the use of a range of mass spectrometric techniques to determine absolute timescales and to trace the sources of components through processes that extend from planetary differentiation to continental weathering and erosion.

a. Low temperature geochemistry: research in this area is aimed at understanding the Earth’s surface environment, both now and in the past. Current areas of research include: Continental weathering and climate change. Quantifying the effects of continental weathering and erosion through the use of a number of key isotope systems, and the study of natural systems. Chemical response of the oceans to changes in source and ocean circulation through direct measurement of seawater, thermal fluids and paleoceanographic records.

b. Planetary evolution: Research in this area is aimed at understanding the formation and differentiation of the Earth and other planets. Current research interests include: use of various techniques for analysing very small samples to high-precision for both conventional long-lived radiogenic isotopes linked to short-lived extinct nuclides to provide key information on early solar system processes. Mantle melting and the generation of oceanic lithopshere. Understanding of element behaviour during mantle melting, timescales of mantle depletion and relationship with crust formation. Assessment of the nature and role of source heterogeneities in the mantle and the influence of magmatic processes on the elemental and isotopic evolution of oceanic basalts.
