EHS Seminar | Colloquium Series | Dr. Peng Gao: Mapping the Human Exposome: From Population Pattern to Cellular Resolution

About

Dr. Peng Gao is an Assistant Professor of Environmental Health and Exposomics at Harvard T.H. Chan School of Public Health. His research focuses on characterizing the human exposome, the totality of environmental exposures and their biological responses, and understanding its role in chronic disease development. Dr. Gao's lab develops and applies advanced analytical chemistry and computational approaches to measure chemical and biological exposures in environmental and biological samples, integrating these with multi-omics data to investigate disease etiology. Before joining Harvard, he was an Assistant Professor at the University of Pittsburgh School of Public Health and completed his postdoctoral training at Stanford University School of Medicine.

Abstract: This presentation will explore cutting-edge approaches in environmental health that integrate chemical exposomics with multi-omics technologies to understand how environmental exposures influence human health. Dr Gao will discuss recent work on precision environmental health monitoring, including longitudinal profiling of personal exposomes and their connections to disease outcomes, with particular emphasis on applications in cancer, neurodegeneration, and respiratory health research. The talk will highlight opportunities for cross-disciplinary collaboration in advancing exposome science across scales, from population-level patterns to individual monitoring and down to molecular and cellular mechanisms.
