Controls on debris-flow avulsions: White Mountains of California and Nevada (2024)
Journal Article

Cosmogenic Nuclide Tracking of Sediment Recycling From a Frontal Siwalik Range in the Northwestern Himalaya (2023)
Journal Article

Cosmogenic Nuclide Tracking of Sediment Recycling From a Frontal Siwalik Range in the Northwestern Himalaya. Journal of Geophysical Research: Earth Surface, 128(12), Article e2023JF007164. https://doi.org/10.1029/2023jf007164

The Himalayan orogen exports millions of tons of sediment annually to the Indo‐Gangetic foreland basin, derived from both hinterland and foreland fold‐thrust belts (FTB). Although erosion rates in the hinterland are well‐constrained, erosion rates in...
