Michelle Walvoord
Michelle Walvoord is a Research Hydrologist for the USGS Water Resources Mission Area.
Dr. Michelle A. Walvoord is a hydrogeologist whose current research focuses on understanding hydrologic response to climate variability and wildfire disturbance. With expertise in non-isothermal, multiphase subsurface flow and transport, she has led a variety of process-based vadose zone and groundwater studies in systems ranging from mid-latitude deserts to high-latitude boreal forests. Her research relies on a blend of field, statistical, and physics-based modeling approaches and typically intersects with multiple disciplines including biogeochemistry, ecology, and geophysics.
