Advanced Characterization Postdoc

Overview

What You Will Do MST-8 is seeking a highly motivated postdoctoral researcher to conduct experimental investigations of plastic deformation and deformation twinning in structural materials, with emphasis on quantifying and analyzing microstructural and twin networks. The successful candidate will lead in situ and ex situ experimental campaigns to uncover how grain connectivity, twin nucleation, and evolving twin networks govern strain localization, hardening, and damage initiation.

The project will focus on high-resolution microstructural characterization and mesoscale mechanical testing to explicitly map grains, grain boundaries, twins, and twin boundary networks during deformation. The goal is to establish quantitative, network-based descriptions of microstructure and twin connectivity and directly link these to measured local plastic response. The candidate is expected to disseminate results in leading journals in materials science and mechanics.

Strong scientific writing skills and the ability to clearly articulate mechanistic insight is essential. The candidate will collaborate closely with computational researchers developing crystal plasticity and network-based modeling frameworks, providing high-quality experimental datasets for validation and mechanistic interpretation.

Minimum

Job Requirements:

• Demonstrated expertise in experimental plasticity of metals.
• Strong knowledge of deformation twinning mechanisms and twin boundary physics.
• Expertise in EBSD analysis, including twin identification and grain boundary characterization.
• Experience with in-situ SEM mechanical testing and microstructural evolution studies.
• Demonstrated knowledge of metals deformation behavior and microstructure-property relationships.
• Evidence of peer-reviewed publications in relevant journals.

Desired

Qualifications:

• Experience analyzing slip-twin interactions and twin network evolution.
• Experience with high-resolution strain mapping techniques (e.g., digital image correlation).
• Experience with 3D microstructure characterization or serial sectioning methods.
• Experience preparing metallographic samples for EBSD and in situ testing.
• A strong publication record demonstrating the ability to independently drive projects to high-impact outcomes.
• Experience collaborating in multidisciplinary experimental-computational research teams.

Education: A PhD in nuclear engineering, materials science, physics, or a related engineering discipline completed within the last 5 years or soon to be completed.
