Dr. Zhang is the author of the textbook entitled "Fundamentals of Environmental Sampling and Analysis" published by John Wiley & Sons, which has been adopted by many universities as the textbook. He has published over 70 peer-reviewed papers, 6 books and book chapters, and 90 conference presentations, and was the recipient of President's Distinguished Research award. Dr. Zhang is the member of American Chemical Society (ACS), Society of Environmental Toxicology and Chemistry (SETAC), Association of Environmental Engineering and Science Professors (AEESP), and National Society of Professional Engineers (NSPE). He is also actively involved in professional services, including Editorial Board member, peer reviewer for over 35 journals, proposal reviewer panels for National Science Foundation (NSF), NSF/USDA, the U.S. Geological Survey (USGS), Strategic Environmental Research and Development Program (SERDP, a consortium of U.S. EPA-DoD-DoE), LSU BP Gulf Research Initiative (GRI), Mississippi-Alabama Sea Grant, Israeli Ministry of Science, Technology and Space, Singapore National Research Foundation, and session chair for numerous conference sessions.

Areas of Expertise

Dr. Zhang's General Research Interests include Environmental sampling and analysis; Environmental chemistry; Environmental remediation; Fate, transport, and remediation of organic chemicals and heavy metals in soil, groundwater, and sediment. Some past and on-going research projects include: Sustainable remediation; Analysis of emerging contaminants (endocrine disrupting chemicals; bromate); Biodegradation of surfactants, explosives chemicals, pharmaceutical and endocrine disrupting compounds; Sorption of polycyclic aromatic hydrocarbons, explosives and endocrine disrupting compounds in soil and sediment; Effects of surfactants on air-water partition of chlorinated solvents; Zero-valent iron for the remediation of chromium contaminated soil and sediment.

Research Projects

Dr. Zhang's research interests are in the areas of fate, transport, analysis and remediation of legacy and emerging contaminants. Research from his group and collaborators has filled the data gaps of the large-scale spatial and temporal distributions for several groups of legacy contaminants (DDT, PCB, and HCH), which are crucial for assessing the risk and human health effects of these persistent organic compounds (POPs). A significant component of his recent research has geared toward the endocrine disrupting compounds (EDCs), such as in the wastewater treatment plants and under the advanced oxidation condition, and in vitro and in silico study on structural-activity relationship of ECDs (MTBE, bisphenol A, flame retardant, phthalate esters, and pharmaceutical and personal care products). These studies are important to help industries modify their operating conditions for optimized removal from the sources, as well as better design safe and environmentally benign green chemicals as a preventive measures. Dr. Zhang's group also keeps abreast of the newest instrumental technologies in partnership with industries to develop new methods for the analysis of trace environmental chemicals in a faster and more reliable way.
