Dr. Kaylin Greene received her Ph.D. in Human Development and Family Studies and Demography from the Pennsylvania State University (2013) and her BA from Whitman College (2006). She completed her postdoctoral training at Montana State University (MSU) and is currently an Associate Professor of Sociology in the department of Sociology and Anthropology at MSU. Dr. Greene’s research interests include health behaviors, daily activities, and well-being during adolescence and the transition to adulthood. Informed by life course and ecological frameworks, her current work examines risk and protective factors associated with substance use, substance use-related harms, and risky sexual behaviors among young people. Methodologically, Greene’s work has used longitudinal and daily diary designs in order to better understand long-term change and short-term fluctuations in activities and behaviors.
