Ammonia (NH3) is the primary form of gaseous nitrogen (N) loss that leads to air pollution, eutrophication, soil acidification, and biodiversity loss. NH3, however, has so far not been subject to equally stringent regulations as sulfur dioxide (SO2) and nitrogen oxides (NOx), despite its increasingly dominant role in gaseous N loss. Xiuming Zhang’s research focuses on the integrated assessment of NH3 mitigation potential costs and benefits both regionally and globally to provide scientific support for policymaking. By developing and applying a multi-model (CHANS, GAINS, GEO-Chem) framework that integrates N cycling, cost-benefit analysis, and scenario analysis, key questions are explored on the cost-effective mitigation pathways and strategies of achieving ambitious NH3 mitigation targets and their co-benefits on improvements in air pollution, human health, ecosystem service and resource efficiency.
Xiuming is currently a PhD student supervised by Deli Chen at the University of Melbourne. She is skilled in data analysis and visualization with different statistical software, ArcGIS, uncertainty analysis, and meta-analysis. Xiuming received a Bachelor of Science and Master of Science in Ecology from Zhejiang University. During her master’s, her research focuses on identifying the role and contribution of NH3 emissions in the formation of PM2.5 and compiling the high-resolution NH3 emission inventory in China with CHANS model, satellite observation, and N deposition monitoring. She is now dealing with the health impact, costs, and benefits of collaborative Nr and GHG reduction scenarios globally. Xiuming works closely with scientists in Australia, China, the US and Europe and maintains an active research agenda in several international and interdisciplinary science projects. She has authored and co-authored about 12 publications in top scientific journals, including Science, Nature communication, Nature food, EST, and EP.
