Selected Quick Facts

As a paleoceanographer, unraveling environmental proxy signals from past warm climate conditions as recorded in marine sediments is my bread & butter. 

Three "warmer-than-present" Epochs of interest:

  • Pliocene (transition from uni-polar to bi-polar ice sheets)
  • Eocene (transition from ice-free conditions to isolated uni-polar ice caps)
  • Late Devonian (ice-free greenhouse climate state). 

Two main proxies of interest: Natural Gamma Radiation & Clumped isotope paleothermometry

Research Interests

My research focus lies on climate - carbon cycle feedback mechanisms (and their changing response to astronomical forcing) under non-Quaternary boundary conditions. For example, on a planet with unipolar ice-sheets, on a planet without 8000 m high Himalayan mountains, on a planet with a wide-open Indonesian Throughflow, or on a planet with more than 500 ppm CO2.

To do so, I study several geological epochs: the Late Devonian (~375 Ma), the Eocene (~40 Ma) and the Pliocene (~5 Ma). None of these time slices are perfect analogues for the Anthropocene, yet they are worth studying as they provide valuable insights into the machinery of the climate system under boundary conditions much unlike today’s. Obviously, the age of the sediment(ary rock) under investigation is very different between the three epochs of interest, but my work always shares a common objective: Integrating the paleoclimate and geochronology aspects of the sedimentary archives to better constrain how much and how fast our planet has been changing. To do so, I draw from my broad skill set (field, lab and numerical modeling) and from a wide range of proxies (isotopic, elemental and geophysical proxies).
