Tian Xia is a Professor of the Division of NanoMedicine at the Department of Medicine at the University of California, Los Angeles and is a part of the California NanoSystems Institute at UCLA. He was named 'Highly Cited Researcher' in 2016, 2018, and 2019 by Clarivate Analytics; was elected as Councilor of the Southern California Society of Toxicology Chapter in 2020; and was named one of the the Top 2% Scientists in Citation in the World Across All Scientific Disciplines 2017–2019 by Stanford. He is striving to gain a fundamental understanding of the molecular mechanisms of interactions between nanomaterials and biological systems, including bacteria, mammalian cells, zebrafish, and mice. The ultimate goal is to apply the information to develop safer and better nanomaterials to satisfy human needs by providing more effective nanoproducts and nanomedicine.
