Marianne Matzke is a senior ecotoxicologist who joined the NERC Centre for Ecology and Hydrology (Wallingford, UK) in 2012, investigating the effects of silver and zinc oxide nanoparticles on natural microbial communities’ structure and function.

This work included also particle-organism interactions and the particles’ fate in aquatic and terrestrial environments. Since then she has been and is involved in several EU projects (NanoFATE, GUIDEnano, NanoFASE, caLIBRAte) all aiming to understand how nanoparticles behave in the environment under realistic conditions and at realistic concentrations to help to develop tools for prospective hazard and risk assessment. Her role in NanoFASE is to look at how microbes influence the particles behaviour and toxicity in the terrestrial (WP7) and aquatic environment (WP8) through e.g. biodegradation (WP5) of the particles coatings or microbial exudates. Another aspect are contributions to WP9 which is dealing with uptake and bioaccumulation of ENMs to higher trophic levels in aquatic and terrestrial environments and how ageing under environmentally relevant conditions influences uptake and bioaccumulation.
