Erica started at NIWA in 1995. After completing a MSc (University of Waikato) developing a blue mussel embryo-larval toxicity test, she spent a number of years in the NIWA freshwater fisheries team. Here she gained skills in fish population studies, the downstream migration adult eels and fish passage through culverts. Her PhD (University of Auckland) investigated the effects of a group of contaminants called polycyclic aromatic hydrocarbons (PAHs) on shellfish. She is currently working on a wide range of projects spanning both the marine and freshwater environments within the National Centre of Māori Environmental Research.
