Biography:

Dr Sarah Marshall joined AUT as a Lecturer in February 2014. Sarah completed a Bachelor of Commerce and Administration in Economics and a Bachelor of Science in Psychology and Operations Research at Victoria University of Wellington. After graduating, she worked in the Australian stockbroking industry before returning to New Zealand to complete a Master of Science in Statistics and Operations Research at Victoria University of Wellington. Sarah completed her PhD in Management Science on the application of deterministic and stochastic models to product recovery systems at the University of Edinburgh in 2012. Sarah taught in the Department of Management Science at the University of Strathclyde in Glasgow for three years before beginning her current position at AUT.  

Sarah is a member of the Mathematical Sciences Research Group and the Data Science Research Group.  Her research focuses on the use of stochastic modelling to address problems of interest to business and industry. Examples of application areas include remanufacturing systems, inventory management and warranty costs analysis.

Sarah has a keen interest in analytics and regularly attends the NZ Analytics Forum.  Sarah is the Industry Liaison for the Master of Analytics and welcomes enquiries from organisations interested in engaging with AUT through student projects. Sarah is a member of the ORSNZ Council and was co-chair of the 2016 Joint NZSA+ORSNZ Conference.
