Postdoctoral Employee - Physics/Astrophysics - Physics Department

Position Overview Saul Perlmutter is Professor of Physics at UC Berkeley and Senior Scientist at Lawrence Berkeley National Laboratory (LBNL), where he is the leader of the international Supernova Cosmology Project, among other initiatives. This postdoctoral position will work with research scientists, engineers, and data scientists and other scholars within his academic and research communities. We are seeking one or more applicants to develop forward modeling software and a characterization and calibration plan for a new space‑based astronomical image slicing spectrograph. The goal is to create and apply a 'digital twin' of the as‑built system to simulate and optimize its performance. Key Responsibilities Develop forward‑modeling software to simulate the spectrograph’s behavior. Design and execute a characterization and calibration plan for the instrument. Collaborate on the creation of a digital twin to mirror the physical system’s performance.
