Job Description
The Advanced Computing Solutions Group in the Computational Science Center at the National Laboratory of the Rockies (NLR) has an opening for a postdoctoral researcher in transportation digital twins, large-scale simulation, and high-performance computing (HPC). The researcher will develop and validate traffic and vehicle simulation models and build scalable computing workflows to study connected and automated vehicle (CAV) operations, traffic control, and their mobility, safety, and energy impacts. The successful candidate will conduct independent research and collaborate with NLR scientists and external partners.
Responsibilities include:
Develop, calibrate, and validate traffic digital twin and co-simulation models.
Design and evaluate vehicle and traffic signal control strategies using optimization or machine learning.
Build and optimize scalable HPC workflows for large-scale simulation and scenario studies.
Integrate traffic, vehicle, communication, and energy models into reproducible research tools.
Analyze results and communicate findings through publications, reports, and presentations.
