Short Biography

Dr. Scharer holds a Ph.D. from the University of Oregon and a B.S. in Geological Sciences from the University of Washington.  She was a professor at Appalachian State University in North Carolina, but most of her fieldwork has been on the geology of southern California.

Dr. Kate Scharer studies active tectonics, with a primary emphasis on the prehistoric occurrence and effects of large earthquakes.  Much of her work is on the San Andreas Fault system, where she has developed long series of paleoearthquake records in order to explore variations in the timing and size of these events.  As part of this research area, she studies tectonic geomorphology and works to improve our ability to radiocarbon date Holocene sediments. Dr. Scharer also investigates tectonics at longer timescales, such as the development and growth of fold and thrust belts.
