Postdoctoral Research Assistant in Photometric Redshift Estimation and Weak Lensing Measurement for Euclid

University of Oxford - Department of Physics

Applications are invited for a Postdoctoral Research Assistant in photometric redshift, spectral energy distribution and weak lensing estimation for ESA’s Euclid mission and LSST.

The post is available initially for a fixed-term duration of 2 years, with the possibility of extension.

This project will develop and test the estimation of photometric redshifts and spectral energy distributions, their effect on the point spread function, and the propagation of errors and biases in the weak lensing experiments on ESA’s Euclid mission and the Large Synoptic Survey Telescope. The successful candidate will be responsible for developing algorithms and testing their effect on the cosmology goals of Euclid and LSST. The post holder will investigate approaches to estimating spectral energy distributions and photometric redshifts from the photometric data available to the Euclid mission, accounting for photometric redshift and SED uncertainties, and the propagation of uncertainties and biases on both photometric redshifts and PSF models into weak lensing analysis with Euclid and LSST. He/she will work as part of a team at Oxford and within the Euclid Consortium and the LSST Dark Energy Science Collaboration. The post holder will have the opportunity to teach.

Applicants should possess, or be close to obtaining, a doctorate in astrophysics or a related field. Previous experience in the field of photometric redshift estimation and/or weak lensing measurement and analysis will be an advantage.

Please direct enquiries about the role to Professor Lance Miller ( and Professor Matt Jarvis (

You will be required to upload a statement of research interests, CV and details of two referees as part of your online application.

Only applications received before 12.00 midday on 19 January 2018 can be considered.

Please note that the University of Oxford's retirement policy has changed. With effect from 1 October 2017, all employees at Grade 8 and above have a retirement age of the 30 September before the 69th birthday. All employees at Grades 1-7 do not have a set retirement age.
