Dr Kai Ruggeri is an Assistant Professor in the Department of Health Policy & Management. He studies fundamental questions of population behavior and decision-making, with a focus on how how integrating behavioral evidence into policies can reduce inequalities and improve population well-being. His recent projects involve behavioral policy studies focusing on large-scale data related to economic choices and related outcomes, which have been covered in media around the world. Collaborating partners include local and national governments, non-profit organizations, industry, and other academic institutions, in New York, various parts of the US, and abroad. Kai joined Columbia from the Department of Psychology at the University of Cambridge, where he directed the Policy Research Group that he founded in 2013. At Mailman, his teaching is primarily in analytics, decision-making, behavioral policy, and managerial economics. He is always happy to meet with students that are interested in getting involved in these topics, whether on the research side, for policy, or in industry. Kai also directs the Junior Researcher Programme, a global initiative for early career behavioral scientists, which is now partnered with the Global Behavioral Science (GLOBES) program he directs at Columbia. He is a Senior Fellow at the Centre for Business Research at the Judge Business School at the University of Cambridge, as well as a Fellow of the Royal Society of Arts and Sciences. Kai completed his PhD at Queen's University, Belfast, in Northern Ireland.

Nudging New York: Federally funded healthcare centers provide medical care to more than 20 million Americans who live in impoverished areas. Yet in many of those areas, nearly half the patients who make medical appointments at the centers are unable to keep their appointments. Data show that patient no-shows, and the missed opportunities for needed medical care, place an enormous health burden on disadvantaged communities. As such, even small decreases in no-show rates at community healthcare clinics will improve the health of vulnerable populations and reduce the nation's medical costs. This work aims to leverage sophisticated methods in data science as well as the growing evidence on behavioral policy to aim to improve access to care in those communities.
