Research interests

I am interested in generating new data for making past climate reconstructions, statistical analysis of this numerical data and data visualisations.

I develop new methods with analytical instrumentation and planktic foraminifera to study variability of phylogeny and geochemistry between individuals and within species. My primary work with the PISTON research project within the Palaeoceanography and Palaeoclimatology research group at the National Oceanography Centre Southampton matures ecology and evolution theories and expands palaeoclimate reconstructions. I work with high temporal resolution sediment core samples and at individual foraminifera chamber resolution to elucidate taxonomic and geochemical changes occurring on the geological and ecological timescales.

I specialise in novel data generation by X-Ray computed tomography, inductively coupled plasma mass spectrometry and stable isotope ratio mass spectrometry. I combine these multi-proxy data into a relational database to make new links through data driven science.

I support 3rd and 4th year undergraduates to contribute to a live research project.

More details about my research, publications and code can be found at https://alexsb1.github.io

Previous projects have included:

  • The characterisation of tar balls collected from beaches in Devon and Cornwall to identify the geographical origin using organic biomarker ratios measured by gas chromatography - mass spectrometry.
  • Method development and optimisation of inductively coupled plasma mass spectrometry for quantitatively analysing metals in seawater.
