Michelle Walvoord is a Research Hydrologist in the Water Cycle Branch of the Earth System Processes Division of the Water Resources Mission Area.
Michelle's areas of expertise include permafrost hydrology, unsaturated zone and groundwater hydrology, and non-isothermal, multiphase flow and transport modeling. Her current research activities are aimed at better understanding environmental impacts on hydrologic systems undergoing change in cold regions. She serves as an Associate Editor for Water Resources Research and as a science steering member the Permafrost Action Team for NSF's SEARCH project. Michelle is an adjunct faculty member at Colorado School of Mines in the Geology and Geological Engineering Department.
