Ethan A. Fosse is currently a Postdoctoral Research Associate at Princeton University in the Department of Sociology and Department of Politics. His research focuses on cultural sociology, demography, and statistical methods, with a particular emphasis on the quantitative analysis of culture. He is working on four interrelated projects, two methodological and two substantive: (1) creating a new set of techniques for identifying age-period-cohort effects, with wide application in sociology and related fields; (2) developing tools such as text regression or, more generally, high-dimensional sparse regression models, to quantitatively analyze textual data; (3) explaining social and cultural change, focusing on the economic, religious, and political views of recent birth cohorts in the United States; and (4) examining the interrelationship between culture and structure, especially the ways in which work and educational institutions influence people's values and beliefs. His research has been published in a number of edited volumes and journals, and he has co-edited a widely-reviewed book on culture and poverty published by Harvard University Press.
As a Postdoctoral Research Associate at Princeton, Ethan develops and teaches the COMPASS Workshops, a series of programming and data analysis workshops. Topics covered include data wrangling, text mining, data visualization, Monte Carlo simulations, and regression modeling. He is also an instructor in the Division of Continuing Education in the Faculty of Arts and Sciences at Harvard University, where he teaches the popular course Introduction to Quantitative Methods for the Social Sciences and Humanities. In creating and teaching this fully-online class, Ethan constructed over forty modules with interactive problem sets, scripts, quizzes, and examinations. As well, with the assistance of a course producer and professional editing team, and funded by a grant from Harvard, he recorded over twenty hours of lectures at the Hauser Digital Studio at Harvard University. For his work on this course he has won an award for excellence in teaching from the Dean of the Harvard Division of Continuing Education.
He has been a Junior Fellow of the American Academy of Political and Social Science, National Science Foundation Graduate Research Fellow, and Doctoral Fellow in the Multidisciplinary Program in Inequality and Social Policy at Harvard Kennedy School. He has held research appointments at several leading academic institutions, including the University of California, Los Angeles and Social Science Research Center in Berlin, Germany. His research has been covered by a wide variety of news outlets and blogs, including The New York Times, The New Yorker, The Huffington Post, and ScienceBlogs. He has also appeared as a guest on NPR Boston with the Governor of Rhode Island and has been interviewed by the Associated Press and the Toronto Globe and Mail.
