PhD Research - Shannon K. Hanna

Shannon K. Hanna's interests lie in understanding how stressors impact the physiology of organisms and how this can affect the ecosystems they inhabit. His background in physiology and biochemistry and his association with the UC Center for Environmental Implications of Nanotechnology allow him to take an interdisciplinary approach in determining the potential impacts of engineered nanomaterials in the marine environment. He works with environmental chemists to understand how nanomaterials will behave in natural waters, conducts experiments to measure changes in demographic and physiological rates in the presence of these materials, and works with modelers to extrapolate his findings to populations and ecosystems.
