Marie Brown


Marie is a consultant Ecotoxicologist at CEA. Her work is primarily focussed on the design and conduct of novel higher tier studies as a GLP study director, including outdoor mesocosm studies, higher tier indoor microcosm community studies, single species studies with non-standard taxa and modified exposure studies.

She has delivered multiple aquatic mesocosm studies with both insecticides and herbicides and is proficient in biological sampling techniques for mesocosm studies and in the identification of freshwater aquatic invertebrates, zooplankton and phytoplankton.

Additionally she has experience of statistically analysing ecotoxicology data including the calculation of MDD values (Minimum Detectable Difference) and ECx values (Effective Concentrations).

Marie’s key areas of expertise are in higher tier ecotoxicology testing and study design as part of a higher tier refinement strategy for environmental risk assessments.
