Current Research Activities
I investigate the mechanisms by which water is exchanged between the coastal oceans and the deep sea. I use mathematical tools, numerical ocean models, and field observations to understand the underlying ocean physics.

My current research involves:
  • understanding ocean dynamics on seasonal and interannual timescales off North and Western Australia, including the 2011 marine heat wave, 2015-2016 bleaching event in the Northern Great Barrier Reef
  • understanding processes that drive upwelling along the Great Barrier Reef.
Expert Committees and Boards
  • IMOS Sub-facility leader: Sensors on Tropical Research Vessels
  • Member of the Australian National Committee for the International Indian Ocean Expedition II (IIOE-2)
