About Nicole M Dennis
I am an environmental toxicologist with a biological and analytical chemistry background. I am broadly interested in how low-dose chronic environmental exposures to real and complex chemical mixtures affect ecosystem and human health. My key focuses are on analytical method development as well as understanding the occurrence, fate, transport, toxicity, and risk of emerging and legacy contaminant mixtures within both aquatic and terrestrial ecosystems.

Research Profile
To date, my research has demonstrated that mixtures of contaminants interact in unpredictable ways, sometimes producing non-additive toxicological effects that challenge traditional risk assessment models. I have identified species-specific bioaccumulation patterns in wildlife, quantified human dietary exposure from biosolids and wastewater applications, and pioneered novel analytical techniques for detecting emerging contaminants in complex environmental matrices. Moving forward, my research program will expand upon my expertise and be guided by several fundamental questions: What mechanisms govern the transport, transformation, and bioaccumulation of organic contaminants in complex environmental matrices? How do synergistic, antagonistic, or additive interactions among chemical mixtures influence toxicity and risk in agricultural and natural ecosystems? And which innovative risk mitigation strategies—integrating analytical methods, laboratory experiments, and field-based trials—can most effectively reduce exposure risks and protect public health? I am developing these inquiries into a research program that integrates mixture toxicology frameworks, exposure science, and ecological risk assessments and creates new methodologies to advance the fields of environmental chemistry and toxicology.
