PhD position in “Bayesian Chronology-Modeling for Paleoclimate archives”


This cutting-edge project at the interface of data-science, statistics and geochronology aims to develop and apply a methodological framework needed to fuse chronologic information from different Earth components into one consistent picture. Different Bayesian statistical models will be combined to synthesize absolute and relative age-information across published timeseries in a flexible and extendable way. This will not only result in a new approach to investigate complex systems in a data-driven way, but also in a consistently dated network of past environmental changes.

This project is part of the Helmholtz School for Marine Data Science (MarDATA) which aims to define and educate a new type of “marine data scientist” by introducing and embedding researchers from computer sciences and mathematics into ocean sciences, covering a broad range from supercomputing and modelling, (bio)informatics, robotics, to statistics and big data methodologies.


  • Develop a Bayesian approach to synthesize stratigraphic information from different paleoclimate records
  • Implement and couple forward models of sediment and tracer deposition from the literature
  • Apply the coupled model to existing environmental records
  • Present at international conferences
  • Publish in peer-reviewed scientific journals


  • a degree (Master’s, Diploma) in mathematics, computer science, physics, climate sciences, or a related field
  • Strong analytical, mathematical and statistical skills
  • proficiency in a programming language (preferably Python, C/C++ or R)
  • excellent English language skills, both written and spoken
  • experience in Bayesian statistics and/or machine learning techniques is a benefit
  • previous experience with (paleo)climate research is an advantage
