Profile

Soil biogeochemist specializing in soil carbon–nitrogen dynamics, microbial ecology, and greenhouse gas emissions under different organic inputs. My work investigates how cover crop–derived organic matter influences soil processes, microbial communities, and agroecosystem sustainability. I integrate biogeochemical assays, molecular techniques, and environmental measurements to inform soil health and climate-smart agriculture.

Research Interests

1. Soil organic matter dynamics and stabilization mechanisms
2. Rhizosphere processes and plant-soil-microbe interactions
3. Ecosystem-level response to climate change
4. Biogeochemical modelling on nutrient cycling
