Dr. Steele specializes in behavioral ecology and aquatic ecotoxicology. She has experience in studying the hydrodynamics of aquatic systems and effects of anthropogenic contaminants on the physiology and behavior of aquatic organisms. She has performed a variety of ecologically relevant bioassays in the laboratory and flow-through mesocosms. Dr. Steele has applied data collected from these and other sources to Individual Based Modelling techniques in order to expand the understanding of anthropogenic impacts on the scale of individuals through communities. Through this work, Dr. Steele has applied a variety of statistical techniques to data from multiple levels of biological organization.

Dr. Steele’s research has worked to further understand the organismal effects of spatially and temporally dynamic contaminant exposures that occur in fluid systems. By examining exposure in laboratory, mesocosm, field, and modelling environments, Dr. Steele has related physiology and ecologically important behaviors (i.e. personality, foraging, agonistic interactions, predator-prey interactions) to the impact of anthropogenic stressors on overall health of aquatic organisms. She has worked in multidisciplinary environments with behavioral ecologists, limnologists, parasitologists, and physiologists. Dr. Steele’s research has focused on exposure scenarios in flowing aquatic habitats, many concepts of fluid dynamics interacting with contaminant exposure can also be applied to terrestrial environments.

Project Experience

Analyzed multiple behavioral responses of field collected crayfish and compared to PFAS contamination levels found at field collection sites to investigate potential of using crayfish as bioindicators for PFAS exposure.

Investigated several behavioral and physiological effects of atrazine exposure in artificial stream systems. Studied enzymatic responses, personality, and agonism displayed by exposed crayfish. Utilized data from bioassays within an Individual Based Model framework to predict possible population impacts of atrazine exposure.

Evaluated toxicological data (acute and chronic toxicity tests) of facility wastewaters to ensure long-term regulatory compliance for Whole Effluent Toxicity (WET) testing.

Performed a literature review on the state of research regarding PCBs and health of wildlife.

Reviewed and evaluated literature on anthropogenic alteration of habitat and the effect on aquatic biota and wildlife.
