Alex Rogers is a marine ecologist who is interested in how biodiversity is distributed in the ocean, especially in the deep sea and on tropical coral reefs. He is also interested in human impacts on the ocean and how to manage human activities to mitigate or reduce degradation of marine ecosystems. His work has taken him to the Indian and Southern Oceans and to the Caribbean investigating coral reef ecosystems, both in shallow water and the deep sea, seamounts and deep-sea hydrothermal vents. Alex has worked with governments, intergovernmental and non-governmental organisations in publicising human impacts, especially those from deep-sea fishing and climate change, and on the development of policy solutions to such problems. He is Scientific Director of the International Programme on the State of the Ocean and a scientific advisor to the Global Ocean Commission.
