Current Research
Two NASA projects fund my current research which generally focuses on modeling C dynamics and comparing different C change estimation approaches to improve management decisions in U.S. forests. In the first project, our aim is to integrate remote sensing and ecosystem models to upscale C measurements in a way that relies heavily on "bottom-up" C measurements for calibration and validation. The second project involves a more detailed analysis of uncertainty and approaches for using FIA data for validation of LiDAR biomass models.
