Postdoctoral Astrophysics Fellowship Opening

Department of Physics Postdoctoral Position in X-ray Astrophysics

The X-ray Astrophysics group of Professor H. Krawczynski at the Physics Department of Washington University in St. Louis is searching for a postdoc working on the XL-Calibur hard X-ray polarization mission, and on the analysis, theoretical modeling, and interpretation of stellar mass black hole, magnetar, blazar, and quasar observations with the Imaging X-ray Polarimetry Explorer (IXPE), the Chandra and XMM-Newton observatories, the Nuclear Spectroscopic Telescope Array (NuSTAR), the Neutron Star Interior Composition Explorer Mission (NICER), and the Neil Gehrels Observatory (NGO). The group is furthermore involved in the development of solid state and microcalorimeter X-ray and gamma-ray detectors. The ideal candidate would have a strong background in one or several of the three areas: theoretical, observational, or experimental astrophysics, and should bring the willingness to work in the other two areas as well. We expect that the candidate will carry through a vigorous research program and will author and co-author research articles in top journals. The initial appointment will be for a two-year year period, renewable for a third year.
Candidates must have a PhD in experimental, observational, or theoretical astrophysics before starting the appointment. Applications should include a curriculum vitae, a list of 2-5 selected publications with a brief description of the applicant’s role in these publications, a 2-page research proposal, as well as the names and contact information for three professional references. Washington University will request reference letters.

The start date of the position is between 7/1/2022 and 7/1/2023. Applicants are encouraged to submit their applications at their earliest convenience through the following Interfolio link: The search will remain open until the position is filled.
