She has been ranked as one of the Top Influential Earth Scientists of 2010-2020, based on citations and discussion of her work. Education Arblaster grew up in Swan Hill, in the Loddon Mallee region of Victoria, Australia. She earned a Bachelor of Technology in Atmospheric Science, from Macquarie University, Sydney, and in 1995 was awarded First Class Honours, also from Macquarie University, for her thesis titled "Investigation of the storm tracks of the mid-latitude regions in an AGCM". Her Honours supervisors were Bryant McAvaney and Ann Henderson-Sellers. From 1997 to 1999 Arblaster studied at the University of Colorado, USA, where she obtained an MSc in Atmospheric and Oceanic Sciences. Her Masters thesis, supervised by Gerald Meehl (National Center for Atmospheric Research) and Andrew Moore (University of Colorado) was titled "Interdecadal modulation of Australian climate in the Parallel Climate Model". From 2007 to 2013 Arblaster completed her PhD at the School of Earth Sciences, University of Melbourne, Australia. Her PhD supervisors were David Karoly, Ian Simmonds (University of Melbourne) and Gerald Meehl. Her thesis topic was "Drivers of Southern Hemisphere Climate Change". Career From 1999 to 2003, Professor Julie Arblaster worked as an associate scientist at the National Center for Atmospheric Research (NCAR). In 2003 she returned to Australia, working with NCAR and the Bureau of Meteorology in Melbourne. Professor Arblaster worked as a senior research scientist from 2003 to 2016 in the climate change processes team at The Centre for Australian Weather and Climate Research, which is a partnership between the Commonwealth Scientific and Industrial Research Organisation and the Bureau of Meteorology. She still maintains her research collaborations with the climate change prediction group at the NCAR. In 2016, Professor Arblaster joined the School of Earth, Atmosphere and Environment at Monash University in Melbourne, Australia. She was promoted to
