Modeling and Data Assimilation




(720) 310-5596


Peter Vaillancourt started as a Reanalysis & Reforecast Associate Scientist in the Cooperative Institute for Research in Environmental Sciences (CIRES) at the NOAA Physical Sciences Laboratory (PSL) in December 2022. His research focuses on model development and data assimilation for coupled reanalysis and reforecasting using the Unified Forecast System, including multi-platform reproducible deployments of models at-scale on HPC systems and in the cloud.

Prior to working at NOAA PSL, he was a Computational Scientist in the Center for Advanced Computing at Cornell University. While there, he developed an interdisciplinary expertise in computational science, physical modeling, applied mathematics, and statistics. A major focus of a few of his past projects was the portability, reproducibility, and automation of scientific computing and HPC applications in the cloud across a variety of scientific disciplines. At PSL, he is focusing on bringing this expertise to weather and climate models to advance our capabilities.
