Sarah is a palaeoclimatologist, geobiologist, and Earth system modeller studying the biogeochemical cycling of carbon between the atmosphere, the ocean, and marine sediments. Particular research interests include rapid carbon cycle perturbations (Mesozoic mass extinctions, Palaeogene hyperthermals), protracted multi-mullion year carbon cycle trends (co-evolution of life and the carbon cycle), and how biogeochemical cycling within marine sediments influences palaeoclimatological and palaeoenvironmental records.

Broadly, my research aims to further our mechanistic and quantitative understanding of how and why carbon moves through the Earth system and how the carbon cycle has changed over Earth history. I employ a range of field geology, laboratory, database, and, especially, modelling techniques to address the following research themes:

  1. Resolving climate and marine carbon cycle feedbacks over rapid to geological timescales
  2. geobiology, biogeochemical cycling in marine sediments and reading the carbonate sedimentary record (in particular stromatolites and authigenic carbonates)
  3. causes, consequences, and carbon cycle perturbations associated with marine mass extinctions
  4. the co-evolution of life and the carbon cycle
