Angelia is currently an Alternate Executive Director on the Board of the International Monetary Fund in Washington DC. She represents the Asia and Pacific Constituency. In addition to Australia, this constituency includes the Republic of Korea, New Zealand, Mongolia, the Seychelles and ten Pacific Island Countries.

 Before taking up her current position, Angelia was the Principal Economic Adviser to the Treasurer. She held this position until November 2020 and was heavily involved in the Government’s immediate response to the COVID-19 pandemic. Prior to this, she was the Head of the Macroeconomic Conditions Division in the Australian Treasury. This Division monitors and assesses economic developments in Australia and key global economies and provides advice to the Government on the economic outlook.

 Angelia has worked in a number of areas across the Australian Treasury since joining the Department in 1999, including as Chief Adviser, Macroeconomic Group and Principal Adviser, Forecasting. She has also previously worked as an economics adviser in the Office of two former Prime Ministers and as Chief of Staff to a former Parliamentary Secretary to the Treasurer. 

 Angelia was awarded a PhD in economics from the Australian National University in 2015.  Her thesis examines the role of particular structural shocks in the United States business cycle, and whether the assumption of rational expectations or adaptive learning in a large macroeconomic model for the US economy provides a better model fit. Her thesis also proposes a new econometric method for computing a model selection criterion that is rarely used in applied work given its computational burden. Angelia has published a number of papers in A and A-star journals.
