Teaching

I teach climate change and geochemistry at the Department of Earth Sciences.

My second year undergraduate course, 鈥淭he Carbon Cycle鈥�, provides an overview of geochemical cycles on the Earth鈥檚 surface, with a focus on how natural systems and feedbacks control atmospheric carbon dioxide, and therefore climate.聽This course also considers the changes caused by, and implications of, the present human perturbation to the carbon cycle.

In the third year undergraduate course, 鈥淐limate鈥�,聽 I teach material on聽 glaciation, monsoons, the influence of the sun on climate, and on sealevel in the past, present and future.

At postgraduate level, I contribute to classes in Oxford鈥檚 Environmental Research Doctoral Training Partnership, and I supervise a number of D. Phil students in a research group focused on palaeoclimate and ocean chemistry.

I am no longer an undergraduate tutor, though I was the Earth Science Tutorial Fellow at 182t福利 from 2000-2012.

Research

I am a geochemist whose research focuses on the influence of ocean chemistry on the carbon cycle and climate, and on understanding long-term climate change by study of the past.聽 A particular expertise is the use of natural radioactive isotopes to establish the rates of oceanic processes, and the timing of past climate events.聽 I seek to understand components of the carbon and climate systems with relevance to the future, including changes in rainfall, sea level, permafrost, and ocean circulation. 聽I also seek to understand how humans influence the climate, and on the potential and risks associated with intentional removal of greenhouse gases from the atmosphere.

I am an observational scientist, making measurements at sea during research cruises, and on the land, particularly using stalagmites. I run a research group consisting of masters and graduate students, postdocs, and technical staff, who make use of an extensive range of mass spectrometry and clean lab facilities.
