Dr Tom Bridge works on the biodiversity of corals on coral reefs, with specific interests in biogeography, ecology and conservation. He is Senior Curator of Corals at the Queensland Museum, and also a Research Fellow at the Australian Research Council Centre of Excellence for Coral Reef Studies at James Cook University. Tom has surveyed corals across many locations in the tropical Indo-Pacific, including Indonesia, Papua New Guinea, the Maldives, the Red Sea and of course the Great Barrier Reef. His particular area of expertise is the reefs of the ‘twilight zone’, which occur in deep, dark waters below normal scuba diving depths and have only recently been surveyed using robots and new, advanced diving equipment. Tom is responsible for the coral collections at the Museum of Tropical Queensland in Townsville, one of the largest and most important coral collections anywhere in the world.
