The Centre for Leadership, Ethics and Organisation (CLEO) is an interdisciplinary research centre based at Queen’s Management School, Belfast. It aims to promote management and organisational studies (MOS) research into issues relating to leadership, ethical management practices including decision making and sustainability, and organisational development / transition. The Centre seeks to explore these areas within the wider research context of grand challenges, wicked problems and system wide change. Global concerns such as climate change, the recent experience of the pandemic, the impact of AI, international terrorism, mass migration between continents and countries, the injurious behaviour of financial institutions all have implications beyond individual and even groups of organisations and institutions. The Centre will seek to frame its activities and actions in the light of these global, interconnected, system wide problems.
