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.
