The William H. Miller Ill Department of Physics and Astronomy at Johns Hopkins University (JHU) invites applications for one postdoctoral fellow position to pursue research in time-domain multi-messenger astrophysics with emphasis on data science and Al. The postdoctoral fellow will lead a project focused on developing optimized strategies for observing, processing, and archiving the datasets from current and future large astronomical facilities, with emphasis on radio interferometric arrays, in the pursuit of multi-messenger transients. Key to this project will be the application of Al techniques to streamline the translation of high-level science objectives into concrete observational and computational strategies. This work will be carried out under the supervision of Professor Alessandra Corsi, in close connection with collaborators at the JHU’s Institute for Data-Intensive Engineering and Science (part of the new Data Science and Al center), and at the National Radio Astronomy Observatory.

Required qualifications are:
– PhD in Astronomy, Astrophysics, Physics, or a related field.
– Previous experience in data science, data reduction and analysis, and/or software development.
– Established record of independent research.
– Research expertise in time domain and/or multi-messenger astrophysics.
– Interested in developing new capabilities for observing and data processing of multimessenger transients with modern astronomical data systems and ML/AI models.

Preferred qualifications are:
– Experience with radio interferometric observing, data processing, and imaging
– Experience with modern machine learning/ deep learning techniques and software packages.
– Experience with time-series data of astronomical transients, including gravitational wave data analysis.
– Experience with high-performance or high throughput computing (HPC/HTC).

The initial appointment is for 1 year. It is anticipated that the position will be renewed annually based on satisfactory performance, for a maximum of three years. Applications will be reviewed as received, starting September 30, 2025, and will remain open until the position is filled.

Applications consist of a curriculum vitae, publication list and a description of past research and future interests (maximum of 3 pages including figures and references). Applicants should also arrange to have two or three letters of reference submitted by the same date. The start date is subject to negotiation, but preference will be given to candidates who can start no later than August 2026.

The Experimental Particle Physics group at the Johns Hopkins University is accepting applications for a postdoctoral fellowship position focused on the CMS experiment at the LHC.

The CMS group at JHU (Profs. Gritsan, Maksimovic, Swartz) has played a significant role in discovery and characterization of the Higgs boson, pursued searches for new beyond-the-standard-model phenomena and tests of electroweak theory, and engaged in development of phenomenological tools for LHC data analysis. The postdoctoral researcher is expected to take a leading role in analyzing Higgs boson data from the Run-3 dataset, contribute to the calibration and alignment of the CMS silicon pixel detector, and participate in the Phase-2 upgrade of the silicon pixel detector. A successful candidate will hold a PhD in experimental particle physics and will have proven expertise in advanced data analysis and phenomenological techniques applied to LHC data, in accordance with the duties outlined above.

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 Gritsan at [email protected]. Consideration of applications will begin on September 1, 2025, and continue until position is filled.

The Department of Physics and Astronomy of the Johns Hopkins University invites applications for postdoctoral appointment in astrophysics, in strong gravitational lensing and supernova science.

Lou Strolger and Armin Rest in the analyses of strongly lensed supernovae and high redshift supernovae, primarily from the Nancy Grace Roman Space Telescope, the Euclid Space Telescope. Candidates should have strong familiarity with transient science, cosmology, and statistical analysis, and have strong software skills.

Consideration of applications will begin on June 1, 2025, and will continue until the position is filled. It is anticipated that the position will be filled at the rank of Johns Hopkins assistant research scientist, with competitive salaries and generous benefits. We anticipate that the positions will be renewed annually based on satisfactory performance, for an expected total of three years.

Johns Hopkins University is committed to the active recruitment of a diverse faculty and student body. The University is an Affirmative Action/Equal Opportunity Employer of women, minorities, protected veterans, and individuals with disabilities and encourages applications from these and other protected groups. Consistent with the University’s goals of achieving excellence in all areas, we will assess the comprehensive qualifications of each applicant.

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/.
