The author of four books and more than one hundred journal articles, Dr. Green studies a wide array of topics: voting behavior, partisanship, campaign finance, hate crime, and research methods. Much of his current work uses experiments to study the ways in which political campaigns mobilize and persuade voters. 

He was elected to the American Academy of Arts and Sciences in 2003 and was awarded the Heinz I. Eulau Award for the best article published in the American Political Science Review during 2009. In 2010, he helped found the Experimental Research section of the American Political Science Association and served as its first president. He moved to Columbia University after spending 22 years in the political science department at Yale University.
