Water Program
Research
The work I have done could not have been done without my numerous excellent (and ever growing) collaborators including: Dr. Josh West. Dr. Marin Clark, Dr. Marcia Macedo, Dr. Dimitrios Zekkos, Dr. Deepak Chamlagain, Dr. Billy Medwedeff, Maddie Hille, Sabin Tiwari, Kirk Townsend, Dr. Takahiro Hosono and Dr. Ide Kiyoshi. Additionally, I am always grateful to the people who live in the Melamchi Valley in Nepal for allowing me access to their lands and springs.
Critical Zone and Water in the High Himalaya
Mountains are the water towers of the world- providing critical water resources to billions of people who live downstream of them. My research has focused on quantifying the age subsurface waters using multiple groundwater dating techniques, understanding critical zone architecture development and deep chemical weathering (water/rock interactions) and soil development in the Nepal Himalaya.
Disturbance Hydrology
Humans have been altering our environment and streams massively for decades through climate change, land use changes (agriculture), deforestation for mining and other extractive processes. I have worked in a variety of disturbance environments including post-wildfire landscapes, mining zones in the Amazon and land conversion in Brazil. My work broadly focuses on how these disturbances effect surface and subsurface flow dynamics, water quality and thermal regimes.
Tools
I utilize a variety of techniques in my research including:
Water isotopes, water chemistry, near surface geophysics (electrical resistivity tomography), remote sensing, cosmogenic dating, petrography and more!
