Dr. Saba initiates diverse, multidisciplinary projects in order to address both small-scale (individual organism) and large-scale (whole ecosystem) questions with ecological, physiological, and biogeochemical implications. Her broad research interests are in the fields of coastal marine organismal ecology and physiology, with emphasis on how organisms interact with their environment (physical-biological coupling) and other organisms (food web dynamics and predator-prey interactions), how physiological processes impact biogeochemistry (nutrient cycling and carbon sequestration), and how climate change (i.e., ocean acidification, warming) impacts these processes. She applies multiple techniques and collaborates with physical/biological/chemical oceanographers and physiologists, molecular ecologists, fisheries scientists, ocean observers, and climate modelers. She employs an integrative, mechanistic approach and has strong laboratory and field components in her research.
