Job Description

About the Role

The University of Sussex is offering an exciting opportunity for a Doctoral Research Fellow to contribute to cutting-edge cosmology research linked to the Simons Observatory (SO).

This role focuses on theoretical and data-driven studies of the Cosmic Microwave Background (CMB). You will work on topics such as gravitational lensing, power spectrum analysis, cosmological parameter estimation, and likelihood modelling.

Based in the School of Mathematical and Physical Sciences, you will collaborate closely with a local research group led by Antony Lewis, while also engaging with the broader international Simons Observatory collaboration.

The position offers a balance between collaborative work and the freedom to pursue your own independent research ideas.

What You Will Work On

Analysis of CMB data from the Simons Observatory
Research on CMB lensing and cosmological parameter estimation
Development of statistical and computational tools for cosmology
Contribution to large-scale collaborative research outputs
Exploration of independent research directions within cosmology

About You

This role is ideal for a researcher with strong expertise in cosmology and numerical analysis.

Essential requirements:

  • A PhD in cosmology, physics, or a closely related field
    Strong experience in CMB data analysis
    Advanced numerical and computational skills
    Familiarity with cosmological modelling techniques

Desirable attributes:

  • Experience working on CMB lensing or related topics
    Prior involvement in large collaborations such as Simons Observatory or similar experiments
    Postdoctoral research experience

You should be comfortable working both independently and as part of an international research team.

Research Environment

The School of Mathematical and Physical Sciences at Sussex is a research-driven academic community known for its strength in theoretical and applied sciences.
