Iโm grateful to have Devika Varma and Lisa Schellenberg supporting me as my paranymphs on this special day.
If youโd like to attend the defence in Utrecht, feel free to reach out to me or my paranymphs for an invitation. Please let me know if you would like to receive a printed copy of the thesis.
I hope the paleoceanographic community feels inspired by this work and continues exploring and applying this proxy.
Nearly thereโand excited for what lies ahead! ๐๐
On 26 May, I will be defending my PhD thesis: โReconstruction of the Cenozoic evolution of the hydrogen isotopic composition of seawater using Cโโ alkenones.โ
Join this team! You wonโt regret it! ๐ ๐
Who knows GPlates and could generate me a Paleogeographic world map spanning the Eocene...?
please DMs me
Ammonites survived the end-Cretaceous mass extinction. I always learned that they went extinct. Very cool finding!

๐ผ Iโm seeking a position in Scientific Coordinator/Outreach, laboratory/analytical Research & Development (R&D), or as a Project Manager.
๐งญ I love organizing things โ whether itโs in the lab, managing projects, engaging in science communication, or working out in the field.
Iโm currently looking for a new professional opportunity in the Bremen area โ maybe you can help me with that. If you hear of any suitable positions or just want to reconnect, Iโd be happy to hear from you or see a comment below.

Timeseries of global average air temperature back to the 1780s
How did global air temperatures vary before 1850?
We can now answer this from direct instrumental observations.
The new GloSAT dataset is under review!

But for now - I am on maternity leave till begin 2025๐ถ๐ถ๐๐
Project 4 and 5 go deeper in time - stay tuned for more hydrogen isotope records of alkenones.

My 3. Paper spans the Mid Miocene, one of my favorite record so far, proud that I was able to measure so many samples manually during covidlabrestrictions. For this open-ocean North Atlantic core site we are confident in our surface seawater isotope reconstruction which fits recent publications.
My 2. Paper spans the Pliocene-Miocene, interesting Equatorial Pacific core and time period but it turned out that we are not able to interpret the surface seawater isotopes based on allenones here. But we learned more about the proxy ๐คทโโ๏ธ
My 1. PhD Paper spans the last 20.000 years and we demonstrate that the d2HC37 proxy is reproducible and we provide an interpretation on the surface seawater isotope change.
Past ocean and climate by analysing sediment cores from the seafloor
My PhD project focuses on d2H of alkenones and I tried to combine it to inorganic d18O records and other proxies ๐ค And applied it to different marine sediment cores from different locations and different timespans of the Cenozoic (thousand to million years)
Since my Bachelor I am fascinated by isotopes and marine geochemistry. My first proxy project back then was on oxygen isotopes of ๐ฆteeth then I discovered the world of foraminifera (e.g. 14C, d18O, d13C) and meanwhile digged into the organic geochemistry world.
Prof. is not an official titel in Germany. Only Dr. can be put onto ID as part of your name and thus was/ is part when addressing a name on letters ect.
Hello, I am new to this space and want to introduce myself the next few weeks.
After my Geoscience Master in Bremen, I started my PhD project march 2020, 2 weeks before lockdown as I use to say ๐
, at NIOZ on the beautiful island of Texel ๐๏ธ๐ฆญ
