Joint Analysis in Large-scale Structure Cosmology

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA's missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology. At JPL, the Dark Sector cosmology group focuses on pursuing various strategies to better understand and mitigate experimental and modeling effects on measurements of cosmological parameters, and conclusions drawn about the nature of dark energy and dark matter. The NPP fellow will conduct independent research on the topic of large-scale structure cosmology, ideally with a specific focus on spectroscopic galaxy clustering. They will closely collaborate with the Dark Sector team on projects furthering understanding of dark energy and dark matter cosmology by addressing likelihood analysis, theoretical modeling of the small scales, or observational systematic effects. The position involves working with space-based cosmology missions like ESA's Euclid and NASA's Roman, as well as ground-based experiments like the Dark Energy Survey, focusing on weak gravitational lensing and galaxy clustering.
