He Hongbo, a female researcher born in November 1969,native of shenyang, Liaoning Province. She holds a Ph.D. degree and serves as a research professor. Her research primarily focuses on the biogeochemical processes of soil carbon and nitrogen cycling and transformation. Original breakthroughs have been achieved in expanding the dynamic indicative role of soil microbial metabolites and residues, particularly through the establishment of the microbial necromass-isotope probing technique integrating 15N tracer technology with soil microbial residue analysis, providing novel technical concepts for soil carbon and nitrogen cycling research. Additionally, by jointly applying biomarkers from microbial and plant sources, the dual regulatory effects of different source components on soil organic carbon accumulation and stabilization processes have been thoroughly investigated, thereby advancing research on soil carbon and nitrogen microbial transformation processes and their associated mechanisms. To date, over 200 papers have been published in mainstream soil science and ecology journals, including more than 100 SCI-indexed articles, with over half of these SCI papers published in top-tier journals. More than 30 projects have been led, including topics under the National Key Research and Development Program, General Programs of the National Natural Science Foundation of China, sub-projects of the Strategic Priority Research Program of the Chinese Academy of Sciences, projects of the Chinese Academy of Sciences Cross-disciplinary Innovation Team, and projects of Liaoning Province's "Xingliao Elite Talent Program" High-level Innovation Team. Honors include the Chinese Academy of Sciences Science and Technology Promotion and Development Award, as well as the Second Prize of the Science and Technology Award from the Chinese Society of Soil Science (12th, 14th, and 16th editions).
