Elizabeth Catlos is a geologist in the Jackson School of Geosciences at the University of Texas at Austin. Her research interests are in developing and applying petrochemical and geochemical techniques to the study of lithosphere dynamics. She uses geochemical and geochronological data to create and constrain models for heat, mass, and fluid flow along major fault systems. She is also interested in applying new approaches in mineral equilibria to estimate environmental conditions during dynamic recrystallization. She specializes in accessory mineral geochronology and developing techniques for isotopic microanalysis. She has published widely about how fault systems operate in the Himalayas and Turkey, and how mineral ages time significant events that occurred in the past.
