Senior🎓
Top SchoolChris Marsh is a research scientist and computational hydrologist with 15 years of experience studying how climate change alters the hydrological cycle—particularly in cold regions—based in Saskatoon, Canada. He leads research at Environment and Climate Change Canada and brings a rare blend of field experience (instrument installation and polar fieldwork) and deep modeling expertise from a PhD in Hydrology. Comfortable in both code and water, he has profiled and optimized large land-surface models (MESH/CLASS), developed CRHM-based models for ungauged basins, and contributed backend fixes to the widely used Spack package manager to ensure complex scientific builds work across compilers. His work bridges rigorous academic research and practical software engineering, enabling robust, reproducible hydrological science at scale.
