Professor Ritchie's research interests are associated with tourism risk management. His research has focused on understanding risk from an individual and organisational perspective. His work on organisations explores risk attitudes and response strategies to effectively respond and recover from crises and disasters. He also explores tourist attitudes to risk and their risk reduction behaviour, including beach goers, Australian outbound travellers and potential travellers to the Middle East and in Indonesia. His research projects also examine the factors that influence the formation of risk attitudes and behaviour by using social and organisational psychology theory and concepts. Recently his interests have expanded to include carbon offsetting to understand consumer preferences and adoption of carbon offseting in an aviation context. He currently holds an ARC Discovery Grant and an ARC Linkage grant on this topic area. He has given keynote speeches at over ten international conferences and has supervised 15 PhD students to completion.
