Postdoctoral Research Associate, Department of Geosciences

The Atterholt research group in the Department of Geosciences at the University of Arizona is seeking a Postdoctoral Research Associate to develop and apply fiber-optic sensing, primarily distributed acoustic sensing (DAS), to address problems in the solid Earth. Our research uses ultra-dense seismic observations to investigate outstanding questions in earthquake dynamics and multi-scale Earth structure.

The successful candidate will work with both existing archives of multi-year deployments throughout California, including in southern Cascadia, the San Andreas, and the Eastern California Shear Zone, as well as new deployments planned in California and Arizona. The candidate will have latitude to develop an independent line of research within this scope, in collaboration with the PI.

This position is a year-to-year appointment, expected to last two years, with possible extension contingent on additional funding. This position has a flexible start date, ideally by summer 2027. Candidates are encouraged to contact atterholt@arizona.edu with informal inquiries.

Review of applications will begin on November 1, 2026, and will continue until the position is filled.

The Department of Geosciences is part of the College of Science, a unit aiming to produce knowledge about earth and environmental processes and human-environment interactions at all geographic and temporal scales. Our department focuses on research and education in the nature, genesis, and history of the Earth and its crust, and the evolution of the environment and biota at the Earth's surface. We encourage interdisciplinary approaches to research in the geosciences, both within the department and through interdepartmental programs.

Outstanding U of A benefits include health, dental, vision, and life insurance; paid vacation, sick leave, and holidays; U of A/ASU/NAU tuition reduction for the employee and qualified family members; access to U of A recreation and cultural activities; and more!

The University of Arizona has been recognized for our innovative work-life programs. For more information about working at the University of Arizona and relocations services, please click here.
