About
Keren Ding is an environmental microbiologist whose research centers on the biogeochemical cycling of nitrogen in agricultural soils, with a particular focus on the microbial mechanisms driving nitrous oxide (N₂O) emissions. Her most cited work, "Iron oxides affect denitrifying bacterial communities with the nirS and nirK genes and potential N₂O emission rates from paddy soil" (2019, 43 citations), represents a significant contribution to understanding how soil mineral composition influences denitrifier community structure and greenhouse gas production. In this study, Ding demonstrated that iron oxides selectively shape the abundance and diversity of denitrifiers carrying the nirS and nirK genes, directly linking soil geochemistry to microbial functional potential and N₂O flux. This finding has important implications for developing targeted mitigation strategies in flooded rice systems, which are major sources of agricultural N₂O. Ding's work bridges microbial ecology and soil chemistry, offering mechanistic insights that inform sustainable nitrogen management. Her research continues to advance knowledge of how environmental factors regulate key nitrogen-cycling microbial guilds, with potential applications for reducing greenhouse gas emissions from agroecosystems.
