Dr. Fenstermaker has experience and interests in the use of remotely sensed data to map, monitor, and assess the effect of environmental stressors on vegetation at small and large scales. As Director of the Nevada Desert Research Center, Dr. Fenstermaker oversees the operations of both the Nevada Desert FACE (Free Air CO₂ Enrichment) Facility (NDFF) and the Mojave Global Change Facility (MGCF). Both of these efforts are a component of the Nevada Global Change program, which is a collaborative effort among DRI, UNLV and UNR. Her Ph.D. research focused on developing methodologies to scale leaf and canopy level measurements, such as evapotranspiration, to plant community and ecosytem levels with the aid of remotely sensed data. Other areas of research have focused on the use of remote sensing to map land use/land cover, monitor environmental status and trends, and the development of quality assurance/quality control procedures for spatial data.
