地球表面，环境与能源哲学博士-古气候，海洋学与环境

我们对控制从太古代到全新世的长期和短期气候与环境变化感兴趣。研究的特殊领域包括冰川-冰川间的气候变化，温室-冰室的振荡，突变的气候，长期和短期的碳循环，大气中的氧气释放，物理和化学风化，地球大气的起源和演变，化学海洋学以及地表，深海，浅层地壳和沉积物中的水-岩石相互作用。我们使用各种工具，包括稳定同位素地球化学，元素地球化学，生物地层学，沉积学和地球物理学，来重建海洋和陆地环境中的过去气候。
We are interested in what controls long-term and short-term climatic and environmental change from the Archean to the Holocene. Particular areas of research include glacial-interglacial climate variability, greenhouse-icehouse oscillations, abrupt climate change, long-term and short-term carbon cycling, oxygen evolution of the atmosphere, physical and chemical weathering, origin and evolution of Earth's atmosphere, chemical oceanography, and water-rock interactions in the surface, deep-sea, and shallow crust and sediments. We use a variety of tools including stable isotope geochemistry, elemental geochemistry, biostratigraphy, sedimentology, and geophysics to reconstruct past climates in marine and terrestrial environments.
