Agus Santoso is a senior research associate at the Climate Change Research Centre, and a CSIRO adjunct science leader. He was awarded a PhD in 2006 by the UNSW School of Mathematics and Statistics. Dr Santoso's research aims to unravel the mechanisms that govern climate variability on seasonal to centennial time scales. Research specialities include tropical climate variability and global thermohaline circulation. Dr Santoso is also a project leader at the Centre for Southern Hemisphere Oceans Research (CSHOR) investigating the dynamics and future projections of the El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). Many drought and flood episodes in Australia have been attributed to ENSO and IOD. Dr Santoso is an associate investigator at the Australian Research Council Centre of Excellence for Climate Extremes. He has served in the World Climate Research Programme CLIVAR Pacific Regional Panel, and is an editor for the Journal of Climate of the American Meteorological Society.
