PhD Project: Sensitivity of Past Warm Climates to CO2


In this PhD project, you will develop new records of atmospheric CO2 and changes in the surface ocean temperature. CO2 records will be produced from carbon isotopic fractionation in alkenone biomarkers. New temperature records will be developed from the clumped isotopic composition of coccoliths, calcite plates produced by a family of phytoplankton.


Research Objectives:



  • Develop and refine proxy system models to reconstruct past CO2 levels and surface ocean temperatures.
  • Conduct short mobility research stays with our project partners at Purdue University in the USA to compare new data with results from climate models.
  • Gain experience in teaching, broader science communication, and/or laboratory management by contributing to departmental teaching, outreach, and laboratory tasks constituting up to 10% of the work time.

Your Profile:



  • MSc in Earth Science, Environmental or Atmospheric Science with a strong background in geology and chemistry.
  • Prior work demonstrating a strong interest in paleoclimate and/or organic geochemistry or clumped isotope thermometry.
  • Demonstrated experience in careful laboratory work, ideally in the field of geochemistry, and solid quantitative and data management skills.
  • Strong skills in scientific writing and solid English communication skills.
  • Ability to work productively in a multidisciplinary, international team, and willing to travel for short research stays in the US with our collaborators.
