Profile
I am a soil ecologist interested in the biogeochemical processes that shape the ecosystem responses to global environmental changes. My research strives to unravel the soil carbon cycling and root-rhizosphere interactions in natural and agroecosystems to enhance the resilience and sustainability of these systems.
AWARDS
1. Outstanding Senior Faculty in Teaching Award, College of Agriculture, Forestry and Life Sciences, Clemson University; 2024.
2. NSF CAREER Award-2023
3. Outstanding Junior Faculty in Research Award, College of Agriculture, Forestry and Life Sciences, Clemson University; 2022.
Research Interests
The current research in our lab centers on the following broad themes:
SOIL CARBON CYCLING: We investigate the mechanisms that facilitate the formation and stabilization of soil organic matter in managed and unmanaged ecosystems that are mediated by chemical composition of plant inputs, microbial metabolism and soil mineralogy. In natural ecosystems we study the pathways through which plants create and maintain legacy effects so as to inform restoration practices. Focusing on conventional and low input agroecosystems, we investigate the effect of plant functional types on the quantity, composition and stabilization of soil carbon and the associated nutrient cycling for improving the soil health and productivity of agroecosystems.
ROOT-RHIZOSPHERE PROCESSES: We are interested in understanding the cross-talk between roots and associated microbiome in shaping the various rhizosphere processes that influence the resilience and productivity of ecosystems. Current projects include evaluating these interactions in conventional and low input agroecosystems.
