Research interests

Professor Wirjanto's research interests lie in the intersection between statistics and econometrics. In particular he conducts research in the field of financial time series with a focus on volatility modeling/forecasting and financial risk management, and in the field of financial mathematics with a focus on portfolio optimization in a high-dimensional setting and on global climate change risks.


Professor Wirjanto is trained in econometrics/statistics at Queen’s University at Kingston. Prior to joining Department of Statistics & Actuarial Science and School of Accounting & Finance (in a joint appointment) in 2009, he was a professor of econometrics at the Department of Economics at UW.  He serves on the editorial boards for a number of academic journals such as Austin Statistics, Econometrics, Journal of Mathematical Finance, Journal of Risk and Financial Management and Mathematical Finance Letters.
