Dr. Qiuyan Yu specializes in monitoring ecosystem services and natural resources by harnessing remote sensing, spatial, and data analysis. Remote sensing provides the ability to gather contemporary and historic site-specific and large-scale environmental data using spaceborne, airborne, and unmanned aerial platforms to provide clients with previously unavailable data-based insights.
Dr. Yu has extensive experience in processing and handling datasets from various earth observation systems (e.g. Landsat, MODIS, Sentinel, ICESat-2, GEDI, Worldview, NAIP, airborne LiDAR, and unmanned aerial vehicle) acquired by different technologies (passive and active imaging).
Her experience includes significant ecosystems such as forest, savanna, agriculture, wetland, and aquaculture. Dr. Yu leverages the combination of remote sensing and geospatial analysis in monitoring and assessing natural hazards and risks, for example monitoring the spatial extent and temporal pattern of drought, flooding, fire, and hurricane and their impacts on human society (e.g. houses and infrastructure) and natural resources (e.g. forest).
Integrating her knowledge and expertise in data science and modeling, Qiuyan also promotes public health by conducting statistical analysis and using machine learning models to untangle the environmental and socioeconomical determinants of diseases and under-five mortality rate.
Improved tree height estimation using newly launched LiDAR systems GEDI and ICESat-2 and Landsat and Sentinel; and untangled the determinants of tree and biomass at global scale.
Leveraged ICESat-2 and Sentinel to improve biomass estimation for global drylands and savannas.
Examined the bifurcation of woody cover and its underlying mechanisms at different scale with Worldview and Quickbird.
Mapped the spatial and temporal pattern of heat stress using Landsat and examined the cooling effects of urban vegetation in U.S. cities.
Evaluated the damage of Hurricane Irma on urban forest in Florida with field measurements, remote sensing images, and sociodemographic census data.
Implemented bathymetry mapping to monitor submerged aquatic vegetation in lakes.
Mapped tree canopy cover change, carbon storage and carbon sequestration using airborne LiDAR, high-resolution airborne images for Tampa, Gainesville, Orange County, Florida.Li, H., Wang, C., Yu, Q., & Smith, E.
