Starting date: Fall 2023

We offer:

- a challenging and rewarding research project in the field of paleoclimatology and paleobotany
- an opportunity to work with a world-renowned research group within Germany and access to state-of-the-art laboratory facilities
- 65% of a full Ph.D. position for 4 years, following the German civil servant E13 grouping (TV L-E13) at FU Berlin (including public service benefits)
- a supportive and stimulating research environment that fosters professional development
- opportunities to present research findings at conferences and publish in peer-reviewed journals
- flexible working hours and conditions within a family-friendly work environment
- working in the vibrant city of Berlin
- career training and development opportunities at Dahlem Research School

The Freie Universität Berlin is committed to equal opportunities and actively encourages applications from individuals with diverse backgrounds and minorities underrepresented in science. Severely disabled persons will be given preferential treatment for equal qualification. We are also particularly welcoming applications from qualified women.
The Paleoclimatology working group of the Institute of Geological Sciences at the Freie Universität Berlin is seeking a highly motivated Ph.D. student to conduct research on the reconstruction of paleoenvironmental change during the Eocene epoch in Central Europe. The Eocene is considered an analog for climate change as it will potentially materialize within the coming decades. Specifically, the student will work on sediment samples and fossil plant specimens (i.e., leaves) from the UNESCO world heritage site Messel Pit in Germany to reconstruct CO2 variability based on stomata density, carbon isotope composition, and plant morphology, and biodiversity changes in response to CO2 variability. This project will be conducted within a dynamic and interdisciplinary collaboration framework, including the Senckenberg Forschungsinstitut und Naturmuseum Frankfurt, Senckenberg Research Station Messel Pit, and the University of Tübingen.
- Conduct research on the reconstruction of paleoenvironmental change during the Eocene in Central Europe
- work with sediment samples and fossil plant specimens from the Messel pit to reconstruct CO2, biodiversity, and plant morphology variability
- analyze and interpret data to draw conclusions about past climate and environmental conditions
- publish research findings in peer-reviewed journals and present results at conferences
- collaborate with other members of the Paleoclimatology working group and other researchers involved in the project
- Master's degree in geology or a related field
- Background in paleobotany is desirable but not mandatory
- Interest in geochemistry
- Experience in laboratory work and data analysis
- Good communication skills in English, both written and verbal
- Knowledge of German is advantageous
- Ability to work independently and as part of a team
- Strong organizational skills and attention to detail

PhD position, PASSAGE: Provenance And transport PathwayS of mArine proxy-bearinG particlEs - Salamanca, Spain

Salamanca, Spain
Applications are invited for a PhD Student position for 48 months funded by the European Research Council (ERC) Project “PASSAGE: Provenance And transport PathwayS of mArine proxy-bearinG particlEs”, supervised by Prof. Dr. Blanca Ausín at the Group of Oceanic Geosciences at University of Salamanca.
This is a full-time (37.5 hours a week) PhD contract limited to 48 months.
The gross salary is 1.400 €/month (14 salaries a year) during the first year, 1.450 €/month (14 salaries a year) during the second year and third year, and 1.700 €/month (14 salaries a year) during the fourth year.

Estimated starting date: October/November 2023.
The PhD researcher will contribute to the goals of PASSAGE using a combination of biogeochemical techniques, such as implementation of age-depth models, biomarker quantification and isolation, geochemical characterization of sedimentary particles, and implementation of isotope mixing models and correction of existing records. The PhD researcher will conduct original primary research that will conclude with the production of an original PhD thesis. The PhD researcher will be based at University of Salamanca and enrol the Oceanic Geosciences research group (, which holds extensive expertise in both Oceanography (water-column, sediment traps, and surface sediments) and Paleoclimate studies (climate variability at different time scales). The PhD researcher will benefit from further continuing education, which includes experience and laboratory skills in sampling and both well-established and novel methods in the (paleo)oceanographic field(s), research stays at other field-leading European institutions (e.g., ETH Zurich (Switzerland) and IPMA (Portugal)), and active participation in oceanographic cruises, workshops, and conferences. The PhD researcher is also given the opportunity to gain teaching experience if language and academic background allow.
Assist in oceanographic instrument setup and testing

Participate in fieldwork: oceanographic cruises to sample material

Analyse and interpret hydrographic databases

Conduct geochemical analyses on sediment samples

Formulate additional hypotheses and research questions

Collaborate, discuss data, and exchange ideas with mentors and colleagues

Write high quality research manuscripts for publication in peer-reviewed scientific journals

Disseminate results at international conferences Mentor undergraduate students
We look for a highly motivated and proactive student with a master's degree in Earth Sciences, Marine Sciences, Environmental Sciences, or related disciplines relevant to the position. Candidates are expected to have a strong interest in past climate variability inferred from marine sediments and modern ocean hydrology. Candidates are expected to carry out laboratory work, analytical work, data analyses and interpretation. Programming skills in R or Matlab are ideal.

They should be able to work both independently and within a team. Good understanding, spoken and written English skills are essential to successfully conduct the research. This PhD project implies participation in at least one oceanographic cruise of 2-3 weeks duration in the Iberian margin and a strong laboratory work component.
Deadline: July 17 th 2023

Interested candidates must send (i) a brief CV (maximum 2 pages), (ii) a letter of their research interest and motivation for this position (iii) one recommendation letter, and (iv) transcripts and diplomas of their BAs and MAs degrees to the following email address:

Application from candidates expected to complete their MAs by the end of July/August are also welcome.
