Research Associate in Astrophysics

This position is associated with Dr James Kirk’s Royal Society-funded project, which aims to enable population-level studies of exoplanet atmospheric spectra spanning the full diversity of transiting planets. The successful candidate will contribute to the analysis and interpretation of spectra obtained through Dr Kirk’s involvement in several JWST programmes. Key scientific themes include the formation and evolution of close-in gas giants, the measurement of limb asymmetries, and the characterisation of rocky exoplanet atmospheres. The postdoc will also have the freedom to develop their own research direction alongside the main project goals.  

The position is available from 1 October 2026, with a latest start date of January 2027. The appointment is for two years.

You will hold a PhD in Astronomy, Planetary Science, or Physics or have an equivalent level of professional qualifications and experience. Candidates who have not yet been officially awarded their PhD will be appointed as Research Assistant.

Candidates with experience in exoplanet spectral data reduction or atmospheric retrievals are encouraged to apply. Candidates must satisfy the following essential criteria (non-exhaustive): relevant research experience in exoplanet science; experience in carrying out research of high quality, independently and in a team, evidenced by a portfolio of high-quality research publications; relevant experience in one or more of the following areas: exoplanet atmospheric retrievals or exoplanet spectroscopic data reduction. In addition, familiarity with JWST spectroscopic datasets is desirable.

Please upload a research proposal of no more than three pages, instead of a supporting statement, and provide the names of two referees.
