Na Li

Period: 2025.06-present · From: Northwest A&F University

Na Li is a postdoctoral researcher in the SOMER Group. She received her PhD from Northwest A&F University under the supervision of Prof. Shaoshan An and was previously a jointly trained doctoral researcher in Germany. Her research focuses on soil carbon-nitrogen coupling, microbial carbon fixation, microbial necromass accumulation, and the stability and resilience of soil organic carbon under precipitation variability.

Her previous work used long-term simulated precipitation experiments in semi-arid grasslands of the Loess Plateau to examine nonlinear responses of SOC, particulate organic matter, mineral-associated organic matter, and C/N stoichiometry to changes in precipitation amplitude and duration. These studies highlight the trade-off between long-term carbon storage and recovery capacity under wet and drought conditions.

She has also investigated cbbL- and cbbM-harboring carbon-fixing microbial communities, showing how precipitation shifts regulate microbial diversity, community structure, network interactions, and bacterial necromass accumulation through soil nitrate, SOC, dissolved organic nitrogen, plant biomass, and accessible carbon and nitrogen resources.

In SOMER, she focuses on micro-ecosystem processes, molecular transformation of organic matter, and microbial-derived carbon stabilization during tailing pedogenesis and degraded soil rehabilitation.
