Research Summary

As an isotope geochemist and paleoclimatologist, I use geochemical tracers to explore how the Earth’s carbon cycle and climate system operate. By combining modern process studies, method development, and paleo-reconstructions, my research addresses the interconnected roles of ocean circulation, continental weathering, and ice sheet dynamics in the earth system. Such evidence provides an invaluable context for understanding modern and future anthropogenic changes.

Much of my research has focused on the Pleistocene and Holocene intervals, but I am also interested in earlier periods of the Cenozoic, as well as the shorter timescales of laboratory experiments and modern seasonal changes. I have expertise working with various archives (e.g. ocean sediments, foraminifera, fish teeth, deep-sea corals, speleothems) and multiple isotope systems, including radiogenic isotopes (e.g. Pb, Nd, and Sr), stable isotopes (e.g. C, O), and non-traditional stable isotopes (e.g. Li).

Recent and ongoing research projects include:

  • Millennial to centennial variability in deglacial and Holocene Southern Ocean circulation and carbon cycling, from combined Nd isotopes and radiocarbon in deep-sea corals.
  • Probing past ice sheet dynamics in Antarctica and implications for future sea level, using detrital sediment provenance analysis.
  • Quantifying the response of chemical weathering to past climate change, based on the application of Pb, Nd, and Li isotope tracers in marine archives.
  • Understanding the controls on terrestrial weathering processes, using Li isotopes in cave waters, speleothems, and sediments.

Please get in touch if you are interested in collaborating on any of these topics, or would like to pursue doctoral research linked to any of these areas at UCL.

I sit on the steering committee of the Geochemistry Group, a Special Interest Group of the Mineralogical Society and the Geological Society. Our activities include panel discussions that aim to provide skills training and careers advice for early career researchers - recordings of recent events can be found here.

I also coordinate the London Palaeoclimate Network, which holds monthly seminars and discussions linked to paleoceanography, palaeoclimate, and climate change. Please send me an email if you would like to be added to our mailing list!
