Job Description
The National Laboratory of the Rockies (NLR) is seeking a Postdoctoral Researcher to conduct research at the intersection of machine learning, computer vision, large-scale data analytics, and photovoltaic (PV) system performance. The successful candidate will join a multidisciplinary research team working to develop new methods for understanding how the U.S. PV fleet changes over time. A primary focus of this position will be developing and applying computational methods to identify and characterize changes in utility-scale PV systems using satellite and aerial imagery, large operational datasets, and other geospatial and system-level data. The researcher will develop, adapt, and validate algorithms for image-based identification and change detection and integrate these results with large-scale PV performance datasets. The successful candidate will work closely with researchers in NLR's PV performance and reliability research community and contribute to the PV Fleets research portfolio. The position requires a researcher who is comfortable developing computational methods, working with large and heterogeneous datasets, evaluating algorithm performance and uncertainty, and translating research methods into reproducible scientific software and analyses. The researcher may also contribute to related projects involving PV fleet evolution, repowering and decommissioning, PV end-of-service analysis, material-flow modeling, and PV circularity.
