Welcome

Kosuke Imai (pronounced KOH-skeh ee-MY) is Edith and Benjamin Geisinger Professor of Government and of Statistics at Harvard University. He is also an affiliate of the Institute for Quantitative Social Science. Before moving to Harvard in 2018, Imai taught at Princeton University for 15 years. Imai’s research focuses on solving methodological problems that arise in social science and other fields by developing new statistical and machine learning methods. Imai is the author of Quantitative Social Science: An Introduction (Princeton University Press, 2017).
