Dr. William H. Armstrong

Dr Armstrong joined the Department in Fall 2017 after completing his PhD at the University of Colorado at Boulder. Dr Armstrong is broadly interested in investigating earth surface dynamics, including the behavior of glaciers and rivers, using satellite remote sensing, field study, and numerical modeling. Dr Armstrong's recent work has focused on the process of sliding at the bottom of glaciers, its sensitivity to meltwater production, and how it changes over daily to multi-decadal time scales. Glacier basal motion is an important process to study because it dominates the motion of many glaciers, will influence how glaciers change in a warming world, and is the means by which the shape our spectacular alpine landscapes. Dr Armstrong's research and teaching support the Department's Quantitive Geoscience, Environmental Geology, and Earth System Science tracks.
