Dr. Cullen's research focuses on understanding the fate and function of trace elements in the marine environment and how natural and anthropogenic environmental perturbations affect trace element biogeochemical cycles. The laboratory utilizes inductively coupled plasma mass spectrometry and voltammetric techniques to investigate the distribution and chemical speciation of trace elements in seawater with special focus on the biogeochemistry of cadmium and iron.
