ABOUT

I am interested in applying small area estimation techniques to study mangrove forests in the United States. These ecosystems are very important because of their ability to sequester carbon and mitigate damage from hurricanes and other tropical storms. However, they are difficult to study because of their remoteness and high degree of spatial discontinuity. My broader research interests include carbon cycling, ecosystem health & vulnerability, landscape ecology, geostatistics & geographic analysis, and global change.

My previous research focused on wetlands in the conterminous United States and was conducted while I was a contracted GIS Specialist at the US Geological Survey. I harmonized and validated data from large-scale remotely sensed data products and field surveys (primarily NLCD, SSURGO, NWCA, WoSIS, CCRN data) and modeled soil organic carbon density to improve existing estimates for CONUS wetlands. This tells us more about the amount of carbon sequestered in wetland soils and the amount of land area in different wetland categories, which can be incorporated into models to understand carbon cycling and climate change.
