Research Associate In Planetary Atmospheric Science

University of Leicester; Leicester Forest East; On-site; GBP 38,000 - 44,000; Full time

Job summary

The University of Leicester's Planetary Science Group invites applications for a Postdoctoral Research Associate in planetary atmospheric science. The PDRA will join the JWSTVoyager team led by Professor Leigh Fletcher to study giant-planet atmospheres using JWST and supplementary data, in preparation for ELT and JUICE era observations.

Applicants should have a PhD, an excellent track record in publishing planetary science, and experience with remote sensing and spectral modelling.

Job description

About the role

Infrared observations from the James Webb Space Telescope (JWST) have rapidly become a cornerstone in the current era of Solar System exploration. The Planetary Science Group within the School of Physics and Astronomy is inviting applications for a Postdoctoral Research Associate (PDRA) in planetary atmospheric science. You will join a team led by Professor Leigh Fletcher, and will be supported by a European Research Council (ERC) Advanced Grant known as “JWSTVoyager.” This project aims to study the origins, atmospheres, and variability of the four giant planets using a combination of JWST, ground-based, and Juno observations. This work will ultimately prepare the team to work with data from Europe’s Extremely Large Telescope (ELT) and ESA’s JUICE mission to Jupiter in the 2030s.

The JWSTVoyager programme seeks to compare the atmospheres of the four giant planets, including (but not limited to) investigations of their bulk elemental and isotopic composition as a window on planetary origins; exploration of the ubiquitous banded structure of the giant planets and how the belts and zones differ from world to world; and studies of temporal variability within giant planet atmospheres, from the smallest-scale storms to large-scale circulation patterns. You will have access to existing (and forthcoming) observations from JWST, coupled with cutting-edge data processing tools. You will work to invert infrared and microwave spectra with a suite of radiative transfer and retrieval tools (NEMESIS), using these to derive climatological parameters (temperatures, winds, composition, and clouds), which can then be used to address the core themes of JWSTVoyager.

About you

Successful candidates will be able to evidence a strong track record in publishing planetary science research in peer-reviewed journals; a knowledge of planetary atmospheric science at an international level; and a proven record in problem solving, data analysis, and spectral modelling via code development (preferably in IDL, Python, or Fortran). You should have a PhD in a research area relevant to planetary science, and familiarity with remote sensing of planetary atmospheres. Experience working as an independent researcher, as well as collaboration within scientific consortia, would also be valuable. You should have good written and verbal communication skills in English, and be willing to travel to represent the JWSTVoyager team internationally.
