Abstract
My name is Yixiang Wang. I earned my Ph.D. in Environmental Engineering from the University of Illinois Urbana-Champaign in 2021. My research bridges atmospheric chemistry and public health, focusing on the cytotoxicity, composition, and sources of outdoor and indoor PM2.5, and on identifying effective interventions to reduce exposure-related health risks.
My earlier work employed oxidative potential (OP), a redox-based toxicity indicator, to apportion health risks to specific sources and components of ambient PM2.5. These findings support using oxidative potential as a meaningful indicator for assessing the health risks of ambient PM2.5. Notably, my research revealed that rural PM2.5, often driven by agricultural emissions, can be as toxic as urban PM2.5—highlighting the importance of re-evaluating risk assumptions based solely on particle mass or location.
Currently, I am a Postdoctoral Research Associate at Lehigh University, working with Professor Linchen He on three research projects related to indoor PM2.5:
Portable Air Purifier Study (Completed): This project evaluated the effectiveness of portable air purifiers in reducing indoor PM2.5 toxicity. By quantifying toxic component contributions and applying source apportionment, we demonstrated that purifiers mitigate risks through mechanisms such as particle filtration and suppression of indoor chemistry. This study was published in ACS ES&T Air.
Indoor PM2.5 Modeling: I developed a mass balance model to distinguish the contributions of indoor emissions and outdoor infiltration to indoor PM2.5 levels. The model also estimates the chemical profiles of indoor-generated PM2.5, supporting efforts to identify and manage indoor emission sources.
Urine Metabolomics Analysis: I am developing an LC-MS method to analyze urinary metabolic biomarkers from a cohort study, aiming to uncover biological mechanisms linking indoor air exposure to health outcomes.
I have authored 19 peer-reviewed publications, including 7 as first author. I am seeking faculty or research scientist positions in North America, Europe, or East Asia. (https://scholar.google.com/citations?user=LvxirmYAAAAJ&hl=en)
