LU Jiayu,Male, was born in May 1990 in Shuozhou, Shanxi Province. He is a Ph.D., Associate Research Fellow, and Master's supervisor. His research focuses on rhizosphere ecology and soil ecology. Using carbon and nitrogen stable isotope tracing, he investigates rhizodeposition and the associated priming effects on soil organic matter decomposition and nutrient mobilization in response to global climate changes and ecosystem management practices. He currently serves as a Young Editorial Board Member of the Chinese Journal of Applied Ecology. He has published 11 SCI-indexed papers in leading plant and soil science journals, including Soil Biology & Biochemistry, Geoderma, and Plant and Soil, with a cumulative impact factor of 58.74 and 88 citations. He received the First Prize of the GEO Scholarship of the Chinese Academy of Sciences in 2019, Shenyang Senior Talent in 2021, Outstanding Worker of the Institute of Applied Ecology, Chinese Academy of Sciences in 2024, and the Ninth Outstanding Young Scientific and Technological Talent Award of the Shenyang Branch of the Chinese Academy of Sciences in 2024.
