My dissertation research seeks to understand how forests will respond to increases in drought severity and heatwaves projected under climate change, by studying the impacts of the 2011 drought on the forests and woodlands of Texas. We use remotely sensed imagery to map canopy loss due to drought across Texas. We then use these maps to better inform models to improve our ability to forecast future tree mortality events, following climate change.
My research interests include: Forest disturbance, drought-induced tree mortality, global change ecology, remote sensing, geospatial analysis, landscape ecology, biogeochemistry, and conservation biology
