Education: B.S., UC Santa Cruz; M.S., Ph.D., University of Washington

Margi's research focusses on the formation and evolution of mountain belts from the perspective of structural geology and tectonics. Topics she has investigated range from the accretion of terranes to exhumation of heavily glaciated mountain ranges. Much of her field work has been in the Coast Mountains for British Columbia, where she is currently studying the evolution of the Late Mexozoic to early Tertiary continental arc. Along with structure and tectonics, Margi is interested in how GIS can shape new questions and directions in structure and tectonics. Students are involved in many aspects of her research, traveling with Margi to British Columbia for field work, tackling projects in the lab, or investigating the geology of the nearby Mojave desert.
