In this exciting role, you will contribute to the activities of the Lyman-alpha working group of the Dark Energy Spectroscopic Instrument (DESI) in the Physics Division. Your work will consist of three parts: analysis of DESI Lyman-alpha data, thus contributing to testing and improving the instrumental noise and resolution measurements determined by the spectroscopic pipeline team; development of cosmological simulations; inference of cosmological parameters using simulations and observational data, focusing on dark energy, dark matter and neutrino masses.

The posting shall remain open until the position is filled, however for full consideration, please apply by close of business on January 7, 2022.

What You Will Do:

  • Become an essential member of the DESI science team with regular presentations in working group telecons and collaboration workshops.

  • Take the lead on science projects related to the analysis of the Lyman-alpha data.

  • Interact with LBNL scientists in the physics and the computing research divisions working on related topics.

  • Conduct original research, working productively both independently and as part of a diverse team.

  • Prepare research papers for publication and present results at seminars and conferences.

What is Required:

  • PhD or equivalent in Physics, Astronomy or closely related field.

  • Experience in cosmology, astronomy, or particle physics research.

  • Analysis experience with astronomical spectra and/or imaging data.

  • Strong programming skills.

  • Excellent written and verbal communication skills.
