Diet is a major source of exposure to many environmental chemicals, including PFAS, micro- and nanoplastics, PCBs, heavy metals, cyanotoxins, plasticizers, and mycotoxins. This problem is exacerbated by extreme weather events, which can increase the production of toxicants and facilitate their mobilization and redistribution in the environment. How can we protect ourselves from inevitable environmental exposure? Have you considered that eating clay can be a solution?

Dr. Wang’s research focuses on developing practical mitigation strategies for environmental chemicals of concern to human health. Her most recent research, funded by NIEHS, aims to develop edible clay-based sorbent materials to mitigate dietary exposure to PFAS and prevent their associated toxicity in reproduction and fetal development. This is a critical need, especially for vulnerable populations during susceptible windows of exposure, such as pregnancy, lactation, and developmental newborns.

Personal Bio

Dr. Meichen Wang is an Assistant Professor in the Environmental Health Sciences Department. Dr. Wang is trained as a toxicologist at Texas A&M University, where she earned her graduate degrees in Toxicology and completed her postdoctoral research that was sponsored by NIEHS Superfund and K99 grants. Her research specializes in using multidisciplinary tools in materials science, analytical chemistry, and molecular biology to develop and apply edible clays that reduce human exposure to environmental pollutants in drinking water and food, as well as their associated toxicity.
