Professor Disney teaches Operations Management, Operations Analytics and Lean Operations to MSc and Executive MBA students at Cardiff Business School.

He recently spent 12 months on Research Leave at the University of California, Los Angeles. Professor Disney has previously held Visiting Positions at the Chinese University of Hong Kong and Boston University. He has extensive experience of teaching in-class, on-line and on-site to both Postgraduate and Executive audiences.

Professor Disney's current research interests involve the application of control theory and statistical techniques to operations management and supply chain scenarios to investigate their dynamic and economic performance. Stephen has a particular interest in the bullwhip effect, forecasting and inventory management.

Stephen has advised several of the world's largest corporations on the bullwhip effect and his research has influenced the material flow of at least 1 in every 7 pounds of UK retail sales. He has worked with many companies in the UK, US and Europe and on supply chains that operate globally.
