Jason is Surface Water Section Chief and Sediment Specialist at the Wyoming-Montana Water Science Center.
Jason's training is in fluvial geomorphology and his work typically focuses on the interface(s) between river processes and physical habitats of river-dependent species. He works with stakeholders to develop scientific foundations for decision making in rivers and streams with ongoing or legacy development pressures. This work spans geomorphic settings ranging from low-slope sand-bedded streams of the Midwest United States to canyon rivers of the Colorado Plateau, and land-use settings ranging from the near pristine to those with heavy agricultural and urban land pressures.
