Research interests

  • Conrad's research focuses on rainfall non-stationarity and the advancement of hydrologic guidelines and techniques with climatic change.


Conrad Wasko is currently a McKenzie Fellow at the University of Melbourne. Conrad has undergraduate degrees in both Civil Engineering and Statistics and a PhD in Hydroclimatology from the University of New South Wales. Prior to undertaking a PhD he was a consulting engineer at the Water Research Laboratory. Conrad's primary research area is in the field of stochastic hydrology. His research focuses on the impacts of climate change in hydrology.
