Job Description
We have an opening for a Postdoctoral Researcher to conduct research in computational modeling of energetic materials. Research will focus on applying all-atom modeling techniques to predict mechanical, thermal, and chemical kinetics terms for multiphysics models of material response under extreme conditions, including initiation and detonation. Key aspects involve formulating computational models of material response under dynamic loading conditions and developing computational workflows to rapidly characterize dynamic material properties. You will use statistics and machine learning to analyze massive datasets, extract dynamical properties, and screen for correlated properties. You will be part of an interdisciplinary team that works on making connections between fine-scale (atomistic), mesoscale, and continuum models of highly coupled reactive transport phenomena. Our team utilizes state-of-the-art petascale computing resources at LLNL to perform simulations with billions of atoms. This position is in the Reaction Dynamics Group within the Energetic Materials & Design (EMD) section of the Materials Science Division, supporting the Energetic Materials Center (EMC).
You will
- Contribute to the conception, design, and execution of computational research to address problems in modeling of energetic materials and constituent materials.
- Conduct all-atom simulations to isolate individual mechanical, thermal, and chemical responses of molecular materials and perform large-scale simulations that capture coupled responses.
- Interact with theoretical, computational, and experimental staff working to develop multi-scale models of energetic materials.
- Pursue independent but complementary research interests and interact with a broad range of scientists, both internal and external to the Laboratory.
- Present formal and informal overviews of research progress at regular meetings.
- Document research; write and publish papers in peer-reviewed journals, and present results within the DOE community, at working group meetings, and at scientific conferences.
- Perform other duties as assigned.
Qualifications
- PhD in chemistry, physics, materials science, chemical engineering, or a related discipline.
- Experience in performing particle-based (all-atom and/or coarse-grain) simulations of crystals and/or polymers utilizing high-performance computing.
- Experience in conceiving and implementing new methods, models, and/or analysis approaches applied to particle-based simulations of material dynamics.
- Experience modeling at least one of the following: mechanics of materials, chemical reaction dynamics, or other activated processes.
- Proficient verbal and written communication and interpersonal skills as reflected in published peer-reviewed papers, presentations, and/or teaching lectures.
- Initiative to take on complex problems, with the ability to work both independently and in a collaborative, multidisciplinary team environment.
Qualifications We Desire
- Experience with modeling of energetic materials, polymers, shock physics, and chemically reactive systems.
- Experience in multi-scale simulation methodologies and in connecting atomistic simulation results to experiments and continuum-based modeling frameworks.
- Experience with statistics and machine learning techniques to analyze and screen large datasets.
Additional Information
All your information will be kept confidential according to EEO guidelines.
Position Information
