Julie joined the CSP from Salesforce, where she was a Business Architect Director consulting on the design of digital organisations from a systems perspective.  Systems thinking and operational research have been central to her 30-year consultancy career in Decision Analysis, evolved over a rich range of industry contexts from environmental management to business optimisation.  She is also actively involved in academic research to improve the tools and methods for decision making in novel, unprecedented contexts. Her academic background is in mathematics and physics.

Julie has extensive experience supporting startup companies or new business initiatives. A serial social entrepreneur, she co-founded the Centre for Fundamental and Anomalies Research in 2000, and co-developed the Library of Exploratory Science in 2004.  She has supported the Centre for Systems Philosophy as a pro-bono consultant since its inception.
