Research interests

  • Conrad's research focuses on hydrologic 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 over ten years experience in both consulting and research. He has contributed to the current national guidelines on flood estimation and his research into understanding the effect of higher temperatures on rainfall patterns was awarded the Lorenz G. Straub award for the best PhD thesis globally in water engineering.
