Purdue University and the University of Oregon are looking for a 2-year joint postdoc position to work on passive source velocity model creation and uncertainty analysis for the Cascadia margin with a preferred starting date between August and October, 2023. Specifically, this postdoc will work to synthesize pre-existing velocity models for the region and create a regional-scale seismic velocity model of the onshore and offshore structure of the Cascadia margin down to mantle depths (~200 km). Creating the model will involve 1) analyzing and compiling various passive datasets to constrain regional velocity structure, 2) applying innovative approaches to create a 3D shear-wave velocity model by jointly analyzing different datasets and their uncertainties, and 3) incorporating results from active source wide-angle reflection and refraction datasets into the final model. This model will be used to better understand the geologic and tectonic processes controlling the variable behavior of the Cascadia margin and will also be used by ground motion modelers interested in seismic wave propagation modeling and hazard analysis.?

A highly qualified candidate will be knowledgeable in:?? 

• A variety of passive and active source imaging methodologies?? 
• Bayesian techniques for uncertainty quantification?? 
• Full-waveform modeling and inversion techniques

This position will be split between Purdue University (Jonathan Delph) in Year 1 and University of Oregon (Emilie Hooft, Doug Toomey) in Year 2, and will be part of a larger working group focused on better understanding the structure and hazards of the Cascadia margin.

This is 1 of 3 postdoctoral positions at various universities that will working collaboratively as part of a larger five-year group project for earthquake science and community geophysical models in the Cascadia Subduction Zone. The postdocs will be expected to play a leading role in regular meetings, workshops, and the development of products across the broader project community. Over the course of the five years, there will be an additional 6 postdoctoral scholars, with likely interaction between postdoctoral researchers to further the goals of the group project.

Applicants require a Ph.D. and should submit a CV, 2-3 reference letters, and a statement of research interest and experience relevant to this project for consideration. The review of applications will begin immediately and will continue until July 28. If you are interested in applying, you are encouraged to email Prof. Jonathan Delph (jdelph@purdue.edu ) to express intent as you gather your material. Salary starts at $50,000 per year with potential for a raise in Year 2.

Purdue University is an EOE/AA employer. All individuals, including minorities, women, individuals with disabilities, and veterans, are encouraged to apply.
