Senior postdoc position in weak lensing with Euclid

Leiden Observatory invites applications for a (senior) postdoctoral research position to join the weak lensing group to work on the analysis of Euclid data. The position is funded by an Advanced Grant of the European Research Council that was awarded to Henk Hoekstra, the coordinator of the weak lensing activities of the Euclid Consortium.

The successful applicant will advance the robustness of the weak lensing measurements using actual data and supporting calibration observations, improve the shape measurement pipeline, and exploit the results scientifically. With the launch of Euclid currently foreseen in the third quarter of 2023, the first data are expected at the start of the appointment. The postdoc is expected to support and co-supervise PhD or MSc students, and is encourage to also pursue a personal research program.

The appointment can be for up to five years, depending on the experience of the candidate. The position comes with a competitive salary and an attractive benefits package with additional holiday and end-of-year bonuses. A starting date no later than September 2023 is preferred. The successful candidate must have a Ph.D. by the starting date. The successful applicant will join the Euclid Consortium and also play an active role in the wider Dutch 'Dark Universe Science Collaboration', which includes members of the cosmological simulations group in Leiden. Although the focus is on the exploitation of Euclid data, members of the lensing group are also LSST data right holders.

Leiden Observatory is a lively world-class university astronomy department that covers a wide range of science. Leiden itself, is a charming university town with international flair with easy connections to other European countries.
