Dr. Fleming is a Senior Associate in Exponent's Ecological and Biological Sciences Practice. She applies her training in water quality engineering to assess the ecological risks posed by pharmaceuticals, pesticides, personal care products, industrial chemicals, and emerging contaminants. 

Dr. Fleming has extensive experience preparing environmental assessments for veterinary pharmaceutical products for use in a variety of farming practices and animal species as well as aquaculture in accordance with U.S. and EU regulations. She has developed an expertise in exposure assessment to support environmental assessments that range in complexity from categorical exclusions to watershed-level models. 

In addition to conducting environmental assessments to support product approvals, Dr. Fleming has experience in evaluating ecological risks associated with the production of genetically modified organisms and contaminated sites, including Superfund sites. She has also applied her engineering background to evaluate water and wastewater treatment technologies and effluent toxicity issues.  

Dr. Fleming's risk assessment experience extends to experimental design and data analysis as applied in her research characterizing the metal oxide nanoparticles used in the semi-conductor industry. Her work determining nanoparticle properties including charge, size, and aggregation rate was used to predict behaviors and interactions with biological cells in aquatic environments.

In addition to her work assessing the environmental impact of engineered nanoparticles, Dr. Fleming has also explored potential applications of these particles. Her research involved the evaluation of low-pressure water filtration membranes modified with antibacterial silver nanoparticles. The ability of this modification to decrease bacterial growth and increase energy efficiency was tested in bench-scale laboratory studies.
