Debjani Sihi is a Post-Doctoral Research Associate at the Environmental Sciences Division and the Climate Change Science Institute. She is interested in evaluating the dynamics of soil organic matter decomposition and greenhouse gas emission along aerobic to anaerobic gradients in systems ranging from the tropics and subtropics (El Yunque National Forest in Puerto Rico, Florida Everglades) to temperate and boreal transition forests (Howland Forest and Harvard Forest in NE USA).
Her current research at ORNL aims to develop a genome-informed geochemical model framework for predicting greenhouse emission from tropical soils and wetlands under the supervision of Dr. Melanie Mayes. Her previous work focused on improving understanding of and modeling capacity for interactions of belowground temperature, moisture, and substrate supply that controls the net soil emissions of greenhouse gases using a model-data fusion approach. Before that, she was a graduate research assistant in Wetland Biogeochemistry Laboratory at the University of Florida where she used empirical methods and numerical modeling to understand complex interactions of temperature, substrate quality, and nutrient availability on greenhouse gas production under anaerobic condition.
