Professor Huan Feng is a coastal environmental geochemist with extensive experience in studying source, transport and fate of contaminants in estuarine and coastal systems. His research includes using radionuclides (such as Th-234, Be-7, Pb-210 and Cs-137) as tracers and developing geochemical models for transport and fate of contaminants in riverine and estuarine systems. Professor Feng is also engaged in urban coastal environmental sustainability study by integrating information and developing easily understandable predictive models pertinent to coastal management. Professor Feng is also studying the composition and speciation of chemical compounds and micro-scale structural characterization of materials including sediments and plants using synchrotron radiation techniques. In addition, Professor Feng has been actively collaborating with international researchers in trace element biogeochemical cycle and coastal contamination studies in the Yangtze River intertidal zone, western Bohai Bay and Xiamen Bay in China. In the past, Professor Feng was actively involved in the project of "New York/New Jersey Harbor Contaminated Sediment Processing and Decontamination Technologies” under the federal Water Resources Development Act (WRDA) directed by US EPA Region 2. The goal of the project was to establish treatment facilities for production of beneficial use products from contaminated dredged material taken from the NY/NJ Harbor.
