About the VeWA consortium:

Goethe University Frankfurt and the Senckenberg Society for Nature Research invite applications for twelve research positions within the LOEWE consortium project VeWA (Past Warm Periods as Natural Analogues of our future 'high CO2' Climate); this includes eight PhD and four post-doctoral positions.

Via the LOEWE excellence initiative, the State of Hessen funds internationally visible research consortia with the aim of establishing thematic priorities.

What does VeWA focus on? We are investigating what conditions on Earth might be like under atmospheric CO2 concentrations more than double relative to pre-industrial times. The Paleogene (>35 million years ago) was the most recent geological period with similar atmospheric CO2 as predicted for the end of the 21st century. In VeWA, scientists from geology, geography, biology and climate modelling join forces to quantitatively investigate and model palaeoclimate and palaeoenvironment of the Eocene and late Cretaceous Periods. In 12 subprojects we will study marine and terrestrial proxy archives (e.g. calcifying organisms and sediments), including those of the Hessen World Heritage Site Messel, and compare these results to new state of the art climate model simulations. Our results will be shared through a public outreach initiative, including an exhibition at the Senckenberg Museum.

VeWA includes 12 positions focusing on the following subprojects and institutions:

About this position:

The Senckenberg Gesellschaft für Naturforschung (SGN), a member institution of the Leibniz Association, with almost 800 employees and its headquarters in Frankfurt am Main, is conducting integrative natural history research with leading research institutions in six federal states. The Senckenberg Biodiversity and Climate Research Centre (SBiK-F) explores interactions between biodiversity and climate.

The Senckenberg Biodiversity and Climate Research Centre Frankfurt (Prof. A. Mulch, Paleoclimate and Paleoenvironmental Dynamics) invites applications for a fixed-term position (36 months) available on 1st May 2020 or soon thereafter - for a

PhD position in Terrestrial Paleoclimate (VeWA Project B1) (m/w/d)
(E13 TV-H, 75% part-time, 36 months)

The successful candidate will be part of the LOEWE consortium VeWA (subproject B1) and participate in the career programs at Goethe University Frankfurt. Project B1 will mainly use organic biomarker geochemistry to elucidate temperature and precipitation seasonality during select Cenozoic continental warm periods. The project aims at assessing annually resolved variations in temperature and precipitation recovered from high temporal resolution records. Branched glycerol dialkyl glycerol tetraethers (brGDGT) will be used to reconstruct average annual air temperatures (MAAT) and pH values, whereas seasonal changes in precipitation as an important part of the hydrological cycle will be addressed by compound-specific δD analyses, on both terrestrial (long-chain n-alkanes) and aquatic (short-chain n-alkanes) biomarkers. International collaboration partners are hosted at Utrecht University (NL).

Assistance with academic teaching, e.g. in student field courses, and contributions to the public outreach initiative of VeWA are part of our overall strategic and scientific goals and are hence expected from all VeWA members.

Qualifications: Candidates with a completed Masters degree in geosciences (preferred), environmental sciences, or (paleo-)biology are invited to apply. We seek a highly motivated student with excellent communication skills, both written and oral, in English. In addition, we expect general analytical (problem) solving skills, independence and organizational skills.

Key to the success of VeWA will be cooperation and interaction amongst the VeWA researchers, co-PIs and PIs, as well as VeWA partners, such that teamwork and interpersonal skills are very highly desirable. Goethe University and Senckenberg support the participation in graduate programs at GRADE (Goethe Research Academy for Early Career Researchers) and YoungScientists@SGN. As a team member of VeWA, we offer excellent working conditions, an international multi-disciplinary working environment and state-of-the art research infrastructure including access to biomarker analytical facilities.

Salary and benefits are according to a public service position in Germany (TV-H E 13, 75%). The contract should start on May 1st 2020 and will be limited for 3 years.

The Senckenberg Gesellschaft für Naturforschung supports equal opportunity of men and women and therefore strongly invites women to apply. Equally qualified handicapped applicants will be given preference. The place of employment will be Frankfurt am Main, Germany.

Interested? Please send your application, mentioning the reference of this job offer (ref. #11-20004 (VeWA-B1) by March 2nd 2020 (deadline) by e-mail (attachment in a single pdf document) consisting of a motivation letter, a detailed CV, detailed description of research experience and interests (2 p.), names and addresses of three potential scientific referees, and an abstract of the MSc/PhD thesis (1 p.) to: Senckenberg Gesellschaft für Naturforschung, Senckenberganlage 25, 60325 Frankfurt am Main; E-Mail: recruiting@senckenberg.de . For scientific enquiries please contact Prof. Dr. Andreas Mulch (andreas.mulch@senckenberg.de) or Dr. Iuliana Vasiliev (iuliana.vasiliev-popa@senckenberg.de).
