The Center for the Fundamental Physics of the Universe (CFPU) in the Department of Physics at Brown University will have an opening for a postdoctoral research associate starting July 1, 2023, or earlier if desired. Timing can be negotiated. The position will involve close collaboration with one or more core CFPU faculty members in the field of machine learning for astro-particle physics and/or cosmology. We seek an individual who can complement the existing strengths of the center while bringing cutting-edge skills in machine learning to bear on problems of interest to center members.
