Professor Zhao Dongye is currently Professor of Environmental Engineering at Auburn University in the United States. He is a well-known scientist in the field of environmental nanoscience and technology research in the United States. He graduated from Lehigh University in 1998 with a Ph.D. His research interests include the application of nanomaterials and technologies in environmental cleanup and repair; the fate, migration and impact of engineered nanoparticles in the environment. He has published more than 90 SCI papers. He has cited more than 3,200 times, and his H factor has reached 32. He has invented 6 US patents and has been invited to conduct academic reports for more than 60 times.

For the first time, Prof. Zhao and his team used low-cost, “green” polysaccharides such as starch and carboxymethyl cellulose (CMC) as protective agents for the preparation of zero-valent iron and other nanoparticles. This result is widely used. In this report, Professor Zhao will introduce "the development and application of stable nanomaterials in the field of repairing heavy metal contaminated soil and groundwater." Nanomaterials repairing heavy metal contaminated soil and groundwater is a new method and technology in the field of environmental science. At present, it has attracted extensive attention from scholars at home and abroad.
