Dr. Chang is Professor of Economics at Indiana University. She has studied various time series and panel data models and developed new theories and methodologies useful for inference in a broad range of economic and financial models. Her recent research includes endogenous regime switching models, functional time series, high frequency factor models and their applications in regime switching DSGE models, income dynamics, and empirical asset pricing models with macro factors. She has also applied her new methodologies to analyze energy demand, climate change, and longevity risk. Her research has been published in Review of Economic Studies, Quantitative Economics, Journal of Econometrics, Econometric Theory, Econometric Reviews, Journal of Time Series Analysis, Econometrics Journal, and Energy Economics. She is currently an associate editor of Journal of Time Series Econometrics and Studies in Nonlinear Dynamics and Econometrics, and the coordinator of Midwest Econometrics Group. She has been involved in mentoring junior female economists in various contexts, including CSWEP, FEW, MEG, JWEN and KWEN mentoring workshops, and also serving as a member of International Advisory Board of Association of the Advancement of African Women Economists (AAAWE).
