Research

My research focusses on how the physiology of microorganisms dictates their impact on the natural environment. Specifically I am interested in the broad diversity of microbes which use iron as an energy source, and how their different lifestyles influence the cycling of iron in soils, sediments and aquatic habitats. I am particularly interested in combining molecular biology (proteomics, genomics) with geochemistry to gain a holistic understanding of iron cycling in these systems.

 

Current research topics include:

 

I am always happy to hear from enthusiastic BSc. and MSc students who would like to join me in this research.
