Biographical details

My career began with obtaining a Ph.D. degree from Purdue University. As a graduate student, I was introduced to nonlinear time series econometrics, which I applied to ENSO and price data. The outcome was convincing enough to fulfill my doctoral degree requirements, and interesting enough to motivate the current path of my research agenda.

Research interests

My primary research interests are in nonlinear time series econometrics, with applications to climate anomalies and commodity prices. More recently I have developed interest in assessing the relationship between financial stress and economic activity. Much of my research involves nonlinear econometric modelling and forecasting.
