Job Summary

CU Boulder's PSAAP Multidisciplinary Simulation Center for Micromorphic Multiphysics Porous and Particulate Materials Simulations Within Exascale Computing Workflows has an opening for a Postdoctoral Researcher to conduct extreme-scale simulations at the particle length-scale for fracture and fragmentation of bonded particulate materials with experimental validation and coordination with micromorphic multiscale models.

Successful applicants will have strong written and verbal communication skills, and interest in working with an interdisciplinary team to apply the following to real-world problems:
  • Collaborative software development and devops (Git, continuous integration, etc.);
  • Finite element, discrete element, and material-point discretizations;
  • Computational mechanics/inelasticity; and
  • Scalable data-intensive computing.

The University of Colorado Boulder is committed to building a culturally diverse community of faculty, staff, and students dedicated to contributing to an inclusive campus environment. We are an Equal Opportunity employer, including veterans and individuals with disabilities.

Who We Are

The PSAAP Center at CU Boulder is a Multidisciplinary Simulation Center (MSC) funded by DOE NNSA Advanced Simulation and Computing (ASC) focused on simulating with quantified uncertainty, from pore-particle-to-continuum-scales, a class of problems involving granular flows, large deformations, and fracture/fragmentation of unbonded and bonded particulate materials. The overarching problem is the processing and thermo-mechanical behavior of compressed virgin and recycled mock high explosive (HE) material subjected to quasi-static and high-strain-rates, confined and unconfined compression, in-situ quasi-static X-ray computed tomography, and dynamic (impact) experiments with ultrafast synchrotron X-ray imaging at the Advanced Photon Source (APS) at Argonne National Laboratory. 

What Your Key Responsibilities Will Be

Simulate the thermo-mechanical behavior of bonded particulate materials like mock HE resolving the particle-scale-physics of particle-particle and particle-binder interactions with emphasis on processing and extreme loadings leading to fracture and fragmentation. Numerical methods used include the Material Point Method (MPM), Discrete Element Method (DEM), Finite Element Method (FEM), Smoothed Particle Hydrodynamics (SPH), and the like, and their couplings for extreme-scale (CPU-GPU) computing. The postdoctoral researcher will work with other Center Team members to upscale the particle-scale response to the macroscale through a statistical micromorphic continuum field theory framework, with Machine Learning (ML) to investigate internal state variable evolution equation forms, calibration and validation against experimental data, and verification of the numerical methods. The postdoc will develop collaborative software with devops (Git, continuous integration, etc.), write peer-reviewed journal articles and communicate results at conferences, along with interact with technical staff at LANL, LLNL, and SNL. 

What You Should Know

  • A background check will be required in accordance with the Boulder Campus Background Check Policy. The position can start immediately and is remote-friendly, especially during the pandemic. The position can last up to 3 years.
  • Please send questions to or apply at CU Jobs.
  • All University of Colorado Boulder employees are required to comply with the campus COVID-19 vaccine requirement. New employees must provide proof of vaccination or receive a medical or religious exemption within 30 days of employment.

What We Can Offer

The salary for this position is $60,000 annually. 


The University of Colorado offers excellent benefits, including medical, dental, retirement, paid time off, tuition benefit and ECO Pass. The University of Colorado Boulder is one of the largest employers in Boulder County and offers an inspiring higher education environment. Learn more about the University of Colorado Boulder.
