Josephine Brown's research interests include past and future tropical climate variability and change, with a focus on monsoons, El Nino-Southern Oscillation and tropical rainfall. She uses global climate models to investigate changes in climate over a range of time scales, including the period since the Last Glacial Maximum and past analogues of a future warmer climate such as the Pliocene, as well as comparing palaeoclimate simulations with future climate projections. She completed her PhD in 2004 at the University of Melbourne and was a postdoctoral research fellow at the University of Reading, UK, from 2004-2006, and then at Monash University from 2006-2009. From 2009-2019 she was a research scientist at the Bureau of Meteorology, contributing to the development of climate projections for Australia and Pacific Island nations. In March 2019 she joined the University of Melbourne as a lecturer in palaeoclimate modelling.
