Xiaojia He, Ph.D., is a senior research scientist at the Center for Toxicology and Human Health within UL Research Institutes’ Chemical Insights. His research focuses on systems toxicology, studying how environmental exposures, such as heavy metals and VOCs, affect host-microbiome interactions and human health. Using multi-omics approaches, he aims to identify biomarkers that bridge critical gaps in the exposure-to-disease continuum, ultimately helping mitigate health risks.

Dr. He earned his Ph.D. from the University of Georgia in microbial bioenergetics and redox dynamics, followed by a postdoctoral fellowship at Emory University on heavy metal impacts on the gut microbiome and lung health. He has received multiple honors, including the Annual Award for Outstanding Research Achievement, Dissertation Completion Award, Best Paper of the Year, and Young Investigator Award from various organizations, as well as recognition as one of the World’s Top 2% Scientists by Stanford/Elsevier. He has authored 50 peer-reviewed articles with over 3,000 citations, serves as editor and reviewer for multiple journals, and contributes as a conference organizer and session chair.
