Short Bio

Martyn is a Professor of Hydrology at the University of Saskatchewan, Associate Director of the University of Saskatchewan’s Centre for Hydrology and the Canmore Coldwater Laboratory, and Fellow of the American Geophysical Union. Martyn’s research focuses in three main areas: (i) developing and evaluating process-based hydrologic models; (ii) understanding the sensitivity of water resources to climate variability and change; and (iii) developing the next generation streamflow forecasting systems. Martyn has authored or co-authored over 175 journal articles since receiving his PhD in 1998.
