معرفی
Christie M. Sayes is a Professor in the Department of Environmental Science at Baylor University's College of Arts & Sciences. She also holds adjunct professorships at Texas A&M University's College of Veterinary Medicine & Biomedical Sciences and the University of North Carolina at Greensboro's Joint School of Nanoscience. Her research is centered on environmental health and safety, particularly in nanotechnology and nanotoxicology, with a focus on exposure characterization, material behavior, and hazard assessment across biological and environmental systems.
Her research interests lie at the intersection of advanced materials, human health & safety, and environmental exposure. Dr. Sayes investigates the fate, transformation, and biological effects of engineered nanoparticles using in vitro models such as lung and intestinal co-cultures at the air-liquid interface. Her work emphasizes material characterization, exposure kinetics, hazard identification, and mechanistic toxicology, aiming to develop safer nanomaterials and formulations. She has extensive experience in physicochemical analysis and toxicological screening of nanomaterials, microplastics, and disinfection byproducts.
The trends in her recent publications highlight a strong focus on nanoparticle toxicity, microplastic impacts, inhalation toxicology, and water contaminant interactions. Her studies span antibacterial nanoparticles, oxidative stress mechanisms, cytotoxicity of vaping ingredients, and the biological effects of disinfection byproducts. She frequently employs advanced in vitro models to simulate real-world exposures and assess health risks, contributing significantly to regulatory science and environmental safety.
