John W. Emerson

Chief Data Scientist

John W. Emerson (Jay) is Director of Graduate Studies and Professor of Statistics, Adjunct, in the Department of Statistics and Data Science at Yale University. He studied Economics and Mathematics both at Williams College and subsequently at Oxford University.  He completed his Ph. D. at Yale University before joining the faculty in 2003. 

Professor Emerson has been Principal Investigator and is Lead Statistician on the Yale/Columbia Environmental Performance Index (EPI), which he presented at the 2010 and 2012 World Economic Forums in Davos. He is on several advisory boards in areas of high-performance computing and data science, including the Uptake Technologies, Inc., NORC at the University of Chicago, and the Pharmacy School of the University of Maryland.

Professor Emerson teaches a range of graduate and undergraduate courses as well as workshops, tutorials, and short courses at all levels around the world. Clients include the Census Bureau, the Federal Trade Commission, US Cellular, and Genentech. His teaching and research invariably intersect, often drawing both from timely real-world problems and from collaborative research efforts. For example, he collaborated with the Wall Street Journal in analyzing the infamous stock option backdating scandal. He and his graduate students offer weekly "Statistical Clinics"to support the broader applied research and statistical computing efforts around Yale University.
