Dr. Zhang's research centers on the global biogeochemical cycling of contaminants and their interactions with Earth systems, encompassing mercury, microplastics, PFAS, antibiotics, radionuclides, and other emerging pollutants. His work examines how these pollutants move through and transform within the atmosphere, hydrosphere, lithosphere, and biosphere, influenced by human activities and climate change. The Tulane Environmental Biogeochemistry Modeling Group combines mechanistic knowledge and observational data to develop numerical models for environmental compartments and interfaces, characterizing pollutant budgets, fluxes, transport pathways, and impacts on environmental quality and human health.

As Editor-in-Chief of npj Emerging Contaminants, a Nature Partner Journal, Zhang promotes research on emerging pollutants and their environmental and health impacts. His interdisciplinary efforts contribute to strategies for pollution mitigation and environmental sustainability.
