Dr. Jacobs' research emphasizes the characterization of spatiotemporal land-surface water dynamics (e.g., evapotranspiration and soil-water dynamics) through experimentation and modeling and the advancement of ecohydrology through interdisciplinary studies with collaborators having strengths in soils pedology, vegetation physiology, and ecology. She uses emerging technologies to enhance the understanding of distributed hydrological processes with a specific focus on surface energy flux estimation. This research addresses the knowledge gap regarding evaporative fluxes and the emphasis within engineering practice to improve the spatial and temporal representation of water cycling.

Jacobs also pursues a parallel research effort in ecohydrology. This research combination, hydrological mechanisms essential to climate-soil-vegetation interactions, underlying ecosystem patterns and processes, and ecohydrology, positions her at the cutting edge of one of the "most exciting scientific frontiers". This research area is rapidly expanding with opportunities and funding, at scales ranging from local to global, to explore challenging and unanswered questions regarding ecosystems, biodiversity, and land change impacts.
