Anke Neumann's main research interests are mineral redox reactions and how these processes affect metal(loid)s, radionuclides, and organic contaminants. Her work spans the broad range from understanding fundamental mechanisms of electron transfer at the mineral-water interface to application of redox processes for contaminant transformation or removal, both in natural and engineered environments. A particular focus within Anke's research are iron-bearing clay minerals and Mössbauer spectroscopy.
