Jie Hu is a “Hundred Talents Program” Professor in geotechnical engineering at Zhejiang University, China. He received B.S. degree in geological engineering from China University of Geosciences in 2015 and Ph.D. degree in geotechnical engineering from Zhejiang University in 2020. He served as a visiting scholar at Georgia Institute of Technology in 2019. After two years of postdoctoral research, he was offered a professorship at the age of 29, becoming one of the youngest professors at Zhejiang University. His research focuses on multi-phase flow behavior and engineering control measures in municipal solid waste landfills. He published 20 peer-reviewed papers in top-tier journals including Géotechnique (2020, 2022, 2023), Journal of Geotechnical and Geoenvironmental Engineering, Engineering Geology, Waste Management and Computers and Geotechnics in the last five years. He discovered the formation mechanism of foam-induced high gas pressure in landfills and conducted centrifugal model tests on slope failure induced by elevated gas pressure for the first time. He developed three-dimensional and high-efficiency drainage technology and equipment to prevent environmental disasters in landfills.
