My research interests lie at the interface of soil mineralogy and environmental geochemistry. I use an integrated approach that investigates the mutual controls between mineralogical transformations and (trace) element mobility in systems affected by anthropogenic activities. Specifically, my research explores how changes in redox status and associated iron and sulfur cycling impact the behaviour of contaminants and nutrients in our environment.  I also try to understand how anthropogenic elements themselves control secondary iron and sulfur mineral transformations – an important, but often neglected perspective in contaminant research. Methodologically,  I use field and laboratory experiments and combine them with advanced analytical tools including spectroscopic and microscopic methods to obtain a mechanistic description of soil chemical processes. My research thus provides a fundamental framework for the design of novel remediation approaches to protect our ground and surface water from contamination.

Effective communication of science is vital to developing enthusiasm for STEM and helps to engage the audience in your presentation. I therefore relish the opportunity to share my concepts of powerful science communication in the community. Approach me if you want to arrange a training with me! Past workshop experiences include:


  • 2019 & 2020: 1.5-day workshop “Powerful science communication” for Early Career Researchers at the Bayreuth Centre of Ecology and Environmental Research (BayCEER).
  • 2018: 1.5-day workshop “Presenting your science effectively and with confidence”, offered by the Gender Equity Division of University of Bayreuth (1.5 days).
  • 2017: Two 0.5 day-workshops “Presenting Science” and "Managing the review process" for Early Career Researchers at Southern Cross GeoScience.
