The William H. Miller III 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.  

A position is now available for the experimental axion dark matter search program at Johns Hopkins in conjunction with the HAYSTAC and ALPHA experiments.  HAYSTAC (the Haloscope At Yale Sensitive To Axion Cold dark matter) is a tunable microwave cavity experiment designed to search for axions with masses above 20 μeV, and has pioneered a number of successful innovations in resonators, sub-quantum limited amplification, and analysis.  ALPHA (the Axion Longitudinal Plasma HAloscope) is a next-generation axion search designed to use tunable wire metamaterial arrays to search for axions above 40 μeV, with a range of sensitivity to QCD axions extending across nearly a decade of parameter space.

The successful candidate is expected to participate in the operations and data analysis of the HAYSTAC experiment, as well as in the commissioning, optimization, and development of analyses for the ALPHA experiment.  The candidate is also expected to take a leadership role in JHU-based testing toward the research and development of future upgrades of ALPHA. Candidates should have a PhD in experimental particle physics or the equivalent, and preference will be given to candidates having experience with cryogenics, microwave electronics, and analysis expertise.

Applications should consist of a CV, list of publications, a brief statement of research, and three letters of recommendation.  Inquiries may be sent to Professor Danielle H. Speller at [email protected].

Review of applications will begin June 1, 2025.  Expected start date is August 2025.  For information on benefits, please see https://hr.jhu.edu/benefits-worklife/.

JHU is an equal opportunity employer and welcomes applications from women and members of underrepresented groups.

Applications are invited for a Postdoctoral Fellow position at the Center for Astrophysical Sciences of Johns Hopkins University. The successful candidate will work with Professor Ray Jayawardhana and his collaborators on observational studies of extra-solar planets and/or sub-stellar objects. Candidates with expertise and interests in ground-based high-resolution exoplanet spectroscopy and/or low-resolution spectroscopy of exoplanets and planetary-mass brown dwarfs with the James Webb Space Telescope (JWST) are particularly encouraged to apply.

Group members lead two Large and Long Programs at the Gemini Observatory targeting ultra-hot Jupiters and other exoplanets. Prof. Jayawardhana is also a member of the JWST/NIRISS science team, with ~200 hours of GTO dedicated to exoplanet characterization. In addition, with Drs. Aleks Scholz and Koraljka Muzic, he is involved in two JWST GO programs targeting the lowest-mass free-floating sub-stellar objects. Group members also use data from TESS, Kepler, Subaru, Keck, VLT, and other major observatories.

The position is for one year, with extensions possible for up to two additional years, and comes with a competitive salary and funds for research expenses. Start date is flexible, with a preference for summer or early fall 2025. The JHU Center for Astrophysical Sciences and the adjacent Space Telescope Science Institute form a large and lively astrophysical community.

Applicants should send their curriculum vitae, a description of research interests and plans and a list of publications, and should arrange for three letters of recommendation to be sent electronically to https://academicjobsonline.org/ajo/jobs/27145. Applications are accepted until the position is filled, and those received before May 15, 2025 will receive full consideration.
