The Henry A. Rowland Department of Physics and Astronomy at Johns Hopkins University invites applications for a postdoctoral associate position in Experimental Nuclear and Particle Astrophysics. The Speller group, led by Assistant Professor Danielle H. Speller, focuses on low-temperature searches for physics beyond the standard model, with a concentration on searches for dark matter and neutrinoless double-beta decay. We have a postdoctoral research position available for with the HAYSTAC axion dark matter experiment. HAYSTAC, the Haloscope at Yale Sensitive to Axion Cold Dark Matter, is a tunable microwave cavity experiment that employs state-of-the-art quantum sensing and microwave techniques to search for axions with masses in the range 10 to 100 μeV. The current experiment is housed at Yale Wright Laboratory, and recently completed its first run with a new squeezed-state receiver. Future plans include R&D toward the incorporation of novel microwave cavities, new quantum devices, and the potential expansion to a second experimental site.

The successful applicant will have experience in data analysis, electronics, and low-temperature cryogenic techniques, including low-temperature measurements and dilution refrigeration. Current projects will involve signal processing, analysis, and research and development toward single microwave photon detection, as well as development and planning of a second haloscope to be hosted at Johns Hopkins University.

The applicant will be expected to work closely with graduate and undergraduate students. It is expected that the successful applicant will take the lead in the development of local hardware and software development efforts, and includes working with other members of the group on commissioning future test equipment in the campus laboratory.

Candidates should have a PhD in experimental nuclear or particle physics, or the equivalent, and preference will be given to candidates having hardware and data analysis experience with low-temperature calorimeters and electronics.

Applications should consist of a CV, list of publications, brief statement of research, and three letters of recommendation.

Inquires may be sent to Professor Danielle H. Speller at

Review of applications will begin on December 30, 2020 and will continue until position is filled. JHU is an affirmative action/equal opportunity employer and welcomes applications from women and members of underrepresented groups.
