Academic and Research Interests
Dr. Christie M. Sayes was formerly a professor of toxicology at Texas A&M University. Dr. Sayes maintains her adjunct faculty appointment at Texas A&M in the Department of Biomedical Engineering and the Interdisciplinary Program in Toxicology. She has more than a decade of experience in the fields of nanotechnology and nanotoxicology and has authored numerous publications, including original research, invited reviews and book chapters. She is a member of the Society of Toxicology, the American Chemical Society, and the Society of Environmental Toxicology and Chemistry. She serves on the Editorial Board of the journals Toxicological Sciences, Nanotoxicology, and Toxicology Letters. Recently, Christie was elected President of the North Carolina Chapter Society of Toxicology.
Sayes has proven abilities in providing technical guidance and leadership to students, technicians, and colleagues; a high aptitude for development of complex particle toxicological and biocompatibility basic and applied research projects in cell culture based and animal based models; substantial training in nanomaterial & nanotoxicology research techniques & instruments; significant experience working independently & collaborating across disciplines and organizations; excellent communication and interpersonal skills with colleagues in science and engineering, senior management, and new and existing clients and other funding sources.
The goal of the research performed in her laboratory is to investigate the fate, transformation, and biological effects of nanoparticles and nanomaterial systems. Her group addresses several fundamental issues relevant to the development safe and effective nanomaterials in biological and environmental applications. These issues include, but are not limited to, the following parameters: the importance of material characterization, dose-response & time-course, correlation of in vitro findings to in vivo results, mechanistic & synergistic analyses, developing mathematical and computational models for predicting nanoparticle toxicities, and defining appropriate endpoints in hazard identification and exposure conditions for risk evaluation.
