Doctoral position (f/m/d)

We are seeking a committed early-career researcher for a

Doctoral position (f/m/d)

in the Department of Integrative Earth System Science. The dissertation project will focus on Microplastics in the environment: from laboratory analysis to source attribution modeling.

The successful candidate will join the International Max Planck Research School for Modelling the Anthropocene (IMPRS ModA), which provides excellent support for professional development in both scientific expertise and transferable skills.

This position offers a unique opportunity to work with leading scientists in geoanthropology and to benefit from state-of-the-art research infrastructure while building a strong scientific profile and professional network.

The successful candidate will have the opportunity to shape their research project, for example by focusing more strongly on laboratory-based analysis of existing environmental samples (e.g., river samples from Thuringia or snow samples from Antarctica), on inverse or process-based modelling, and the synthesis of observational data with existing literature.

Tasks

The successful candidate’s responsibilities will or may include:

· Developing original ideas for a multidisciplinary dissertation project (e.g., development of new analytical approaches)

· Conducting laboratory-based analysis of microplastics samples

· Processing datasets for the Great Acceleration Observatory, a data hub for biophysical and socio-economic indicators developed at MPI-GEA

· Potentially participating in fieldwork to collect new samples

· Applying and potentially further developing numerical models for source attribution and transport dynamics

· Collaborating with researchers within the institute and with external partners on microplastics analysis

· Contributing to departmental outputs (e.g., publications, datasets, outreach activities)

Your qualification

_Require_d

• Master’s degree in physics, climate or atmospheric science, chemistry, geosciences, or a related field
• Strong interest in interdisciplinary research on anthropogenic impacts within the Earth system
• Experience in data processing and basic programming skills
• Strong written and oral communication skills, demonstrated through a Master’s thesis and, if applicable, publications or outreach activities
• Excellent English skills

Advantageous:

• Experience with numerical modelling
• Organizational skills (e.g. for outreach activities)

About us

The Max Planck Institute of Geoanthropology (MPI-GEA) was founded in the summer of 2022; it is a dynamically growing, highly-interdisciplinary and international research institution. The research focuses on modeling and analyzing the interrelationships between biophysical and human-made systems, looking from the deep past to the future to examine how humanity has driven the emergence of the Anthropocene – the period in which human activities began significantly impacting our planet’s climate and ecosystems – and identifying potential intervention points towards a more sustainable future.
