Working at NRELNREL is located at the foothills of the Rocky Mountains in Golden, Colorado is the nation's primary laboratory for energy systems research and development.

Join NREL, where world-class scientists, engineers, and experts are accelerating energy innovation through breakthrough research and systems integration. From our mission to our collaborative culture, NREL stands out in the research community for its commitment to an affordable and secure energy future. Spanning foundational science to applied systems engineering and analysis, we focus on solving complex challenges to deliver advanced, secure, reliable, and cost-effective energy solutions. Our work helps strengthen U.S. industries, support job creation, and promote national economic growth.

At NREL, you’ll find a mission-driven environment supported by state-of-the-art facilities, multidisciplinary research teams, and strong collaborations with industry, academia, and other national laboratories. We offer robust professional development opportunities, and a competitive benefits package designed to support your career and well-being.

Job Description

The Advanced Computing Solutions group in the NREL Computational Science Center has an opening for a graduate student researcher in chemo-mechanical modeling with special emphasis on meshfree and particle methods. The researcher will work on adapting a meshfree model of cathode cracking in lithium-ion batteries to the degradation of fuel-cells/electrolyzers. Additionally, the research will investigate methods for improving crack fidelity using ML techniques.

We are looking for a dynamic, motivated researcher with a strong technical background and an interest in the mission of NREL. The successful candidate will collaborate with NREL staff and researchers to develop and apply the necessary modifications to the existing python code such that the system of equations applicable to fuel-cell electrochemistry.

Responsibilities include:

• Assist in the adaptation of meshfree methods for fuel cell/electrolyzer models
• Collaborate with NREL researchers to model and simulate accurately the degradation (cracking) that occurs in electrochemical systems to improve durability and reliability
• Process and visualize results from simulations scenarios to inform research
• Author, present and assist in the preparation of technical papers, reports and/or conference proceedings on topics related to electrochemical-mechanical modeling and simulation
• A stretch goal for this intern will be developing their understanding and utilizing software frameworks to process and ingest data for simulation and application of physics-based and image-based machine learning
