Post Doctoral Research Fellow in CMB Science with Simon’s Observatory(UK Sponsorship)

Job Description

Position Overview

The University of Sussex is inviting applications for a Postdoctoral Research Fellow in Cosmic Microwave Background (CMB) Science. The successful candidate will contribute to theoretical and data-driven research connected with the Simons Observatory, an international collaboration dedicated to advancing cosmology through high-precision observations of the cosmic microwave background.

The position will focus on areas such as CMB lensing, power spectrum estimation, likelihood development, cosmological parameter inference, and other related topics. The role offers the opportunity to work closely with a local research group led by Professor Antony Lewis, while also engaging with the broader Simons Observatory collaboration.

Alongside collaborative work, the fellow will have the opportunity to pursue independent research directions that complement the scientific goals of the project.

Key Responsibilities

The appointed researcher will:

• Conduct theoretical and computational research related to Simons Observatory cosmology analysis.
• Contribute to the development and application of tools for CMB data analysis, including lensing reconstruction and parameter estimation.
• Work collaboratively with the Sussex cosmology team and international Simons Observatory researchers.
• Participate in meetings, workshops, and collaborative research activities.
• Publish research outcomes in peer-reviewed scientific journals and present findings at international conferences.
• Develop independent research ideas that enhance the scientific programme of the project.

Candidate Requirements

Applicants should demonstrate strong expertise in cosmology and data analysis related to the cosmic microwave background.

Essential qualifications and experience include:

• A PhD in Physics, Cosmology, Astrophysics, or a closely related field.
• Strong computational and numerical analysis skills.
• Experience in CMB data analysis, particularly in areas such as lensing, likelihood analysis, or power spectrum estimation.
• Ability to work effectively in an international collaborative research environment.

Desirable experience:

• Prior involvement in Simons Observatory or other major CMB experiments.
• Previous postdoctoral research experience in cosmology or astrophysics.
