Staff Profile

Dr Anke Neumann

Visiting Fellow, Environmental Engineering Group

Background



I am an environmental chemist, investigating mineral redox reactions and how these processes impact water quality. I joined the Environmental Engineering group in 2014 and specialise in research into iron (bio)geochemistry, contaminant transformation and water sustainability. Working at the interface of environmental science/engineering and geochemistry, my research bridges the gap between mechanistic understanding of iron redox processes at the micro- to nanoscale and their practical application for protecting and enhancing the quality and sustainability of water and the environment. Details of current projects can be found on the Neumann Research Group website.

As Secretary and past Chair of the Clay Minerals Group of the the Mineralogical Society, I am also keen to promote service to the community; click here for the CMG website.

Research

Research Interests

My research focuses on redox processes at the mineral-water interface and how these processes impact water quality. My work spans the broad range from understanding fundamental mechanisms of electron transfer to application of redox processes for contaminant transformation or removal, both in natural and engineered environments. Working at the interface of environmental engineering, soil science, and (bio)geochemistry, I am eager to address emerging and transdisciplinary questions related to water sustainability.

My current specific research interests include

* redox reactions in complex biogeochemical environments;

* effects of fluctuating redox conditions on Fe mineral reactivity;

* implications of Fe(II)-induced processes at minerals for contaminant transformation.


To address these research themes, my group uses a variety of techniques to analyze organic and inorganic species in aqueous phase (HPLC, GC-MS, GC-FID, ICP-MS), to characterize mineral phases (infrared spectroscopy - ATR-IR, DRIFT, X-ray diffraction - XRD, Mössbauer spectroscopy, electron microscopy - SEM, TEM), and stable isotopes as process tracers.
