The federal government has picked marine ecologist Ian Poiner to head the Great Barrier Reef Marine Park Authority, an agency which oversees the world's largest collection of coral reefs.

Dr Poiner's most recent roles include chairing the Reef and Rainforest Research Centre (RRRC), a group linking tourism with environmental study that has been criticised for its handling of crown of thorn starfish culling programs funded by the authority itself.

"Dr Poiner is a highly respected marine scientist with international science credentials and board leadership experience," Melissa Price, the federal environment minister, said.

"He has a long history of involvement in Great Barrier Reef science and conservation, and is a former CEO of the Australian Institute of Marine Science," Ms Price said. "I have no doubt he will make a significant contribution to the continued health and resilience of the reef."
