Kai Ruggeri

Senior Research Fellow

Dr Kai Ruggeri is Assistant Professor in the Department of Health Policy & Management at Columbia University and a Senior Visiting Fellow at the CBR, where he is the founding director of the Policy Research Group (originally based in the Department of Psychology). He studies how policy influences population behaviour, and how integrating evidence into policies can improve economic outcomes and population well-being. His teaching is primarily in analytics and decision-making, as well as in behavioural and managerial economics. His current projects involve a number of data-driven policy studies focusing on large-scale behavioural insights related to economic and health choices. With the CBR, he was the PI for the mental health and behaviour in the Lebanon branch of the ESRC grant, awarded under RCUK’s Global Challenges framework (2017-2022). He is a former Fellow at Corpus Christi College and a current Fellow of the Royal Society of Arts.

He has served and continues to serve as an academic expert for industry and government globally, including PwC, the World Economic Forum, the US Food and Drug Administration, the UK Department for Health, NAC Analytica (Kazakhstan), the British Council, and Grand Challenges Canada.
