Dr. Kendra Brown has 8 years of experience assessing the impact of air, water and soil quality on human health and ecosystem function. With expertise in microbiology, she provides consulting and litigation support to clients regarding regulatory compliance under the Clean Water Act and CERCLA. She also advises clients in assessing natural resources damages, interpreting health-based guidance, and designing programs for environmental stewardship. Dr. Brown assesses the human health and ecological consequences of bacterial and nutrient releases via sewage, industrial wastewater, stormwater and agricultural waste. In particular, she uses genetic methods for microbial source tracking to differentiate fecal indicators from human versus non-human sources. She also evaluates harmful algal and cyanobacteria blooms in fresh and saltwater, including the design of monitoring programs and development of regulatory thresholds and approaches.

Dr. Brown also applies her microbiology expertise in areas such as product development, including medical implants, microfluidic devices, and wearable products. She implements studies to monitor microbial growth on surfaces and fabrics. In both environmental and clinical contexts, she understands the strengths and limitations of a variety of microbial assays, including culture, quantitative polymerase chain reaction (qPCR), and high-throughput sequencing assays.

In addition, Dr. Brown has experience applying principles of environmental physics and chemistry to analyze contaminant fate and transport. She investigates the movement of bacteria, dissolved compounds, and non-aqueous phase liquids through unsaturated and saturated soil. She also develops and evaluates models that predict the transport of contaminants in groundwater, surface water, and river sediment.
