A Townsville original, Stephen completed a BSc (Hons) and PhD in the School of Earth and Environmental Sciences at James Cook University in 2000 and 2005, respectively. Stephen is a geochemist that focuses primarily on water quality in the Great Barrier Reef (GBR) catchment area and lagoon including evaluating the sources, transport and risks of various pollutants in freshwater, estuarine and marine ecosystems.
