Research interests

Professor Wu has a primary research interest in the design and analysis of complex surveys. His research also covers more broad topics including semiparametric and nonparametric methods, resampling (jackknife and bootstrap) techniques, missing data and measurement error problems. He has worked extensively on empirical likelihood (EL) methods and related computational procedures, with strong interest in developing R packages for practical implementations of the EL methods.


Changbao obtained his PhD in statistics in August 1999 from Simon Fraser University under the supervision of Professor Randy Sitter. He has been a faculty member at Waterloo since September 1999. He is a Fellow of the American Statistical Association (ASA), an Elected Member of the International Statistical Institute (ISI), and the 2012 recipient of CRM-SSC Prize in Statistics. He is currently Associate Editor of Survey Methodology (since 2006), Biometrika (since 2008) and Journal of Nonparametric Statistics (since 2011). He is also a member of Statistics Canada’s Advisory Committee on Statistical Methods.
