Xiaoqiong completed her Ph. D study at the University of Massachusetts Amherst in April 2018. Her doctoral study focused on interactions of titanium dioxide (TiO2) nanoparticles (NPs) (inorganic nanomaterials presented in food) with food components and mechanistic studies of adverse effects induced by TiO2 NPs.
She joined Dr. Philip Demokritou’s group in July 2018 as a postdoctoral fellow to study the applications and implications of ingested engineered nanomaterials.
- Cellular interactions of ingested engineered nanomaterials and nutrients
- Toxicity of ingested engineered nanomaterials
