My research interests include microbial processes for bioremediation of (in)organic environmental contaminants (mining wastes, agriculture runoff) and the recovery of valuable resources from municipal/industrial wastes.

My area of research is situated at the interface of Molecular Microbial Ecology, Geomicrobiology, and Environmental Biotechnology. In the lab we use classical microbiology and state-of-the-art molecular tools to identify and quantify the ‘lifestyle’ of environmental microorganisms. Through comprehensive ecosystem-level analyses of geochemical parameters, microbial community composition, and in situ functions at various spatial and temporal scales we obtain insights into key microbial-mediated transformation processes in various environments and engineered bioprocess systems.
