The Experimental Particle Physics group at the Johns Hopkins University invites applications 
for postdoctoral Fellowship positions. The William H. Miller III Department of Physics and 
Astronomy has opened several prestigious named Fellowship positions in any area of Physics 
and Astronomy:

Applicants are requested to list the names of faculty members whose interests most closely 
resemble theirs. Consideration of applications will begin on 1 December 2023 and continue 
until all available positions are filled. The target start date of the named Fellowship positions 
is in the Fall of 2024, but an earlier start date will be considered. Applicants will also be considered 
for other appropriate postdoctoral positions in the Department, with a flexible start date. 

The Experimental Particle Physics is one of the areas of focus in the Department. The collider-based
efforts include the Compact Muon Solenoid (CMS) experiment at LHC, fixed-target SpinQuest experiment 
at FNAL, and feasibility studies of a Future Circular Collider. The neutrino and dark matter efforts 
include the Cryogenic Underground Observatory for Rare Events (CUORE), the CUORE Upgrade with Particle 
Identification (CUPID), the Haloscope at Yale Sensitive to Axion Cold dark matter (HAYSTAC), studies 
of DArk Matter In CCDs at Modane (DAMIC-M), R&D for the search for low-mass dark matter with CCDs 
(OSCURA), and R&D efforts on future microwave and bolometric detectors. 

The CMS group (Profs. Gritsan, Maksimovic, Swartz) has played a significant role in discovery and 
measurement of spin-parity and other properties 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. There is a possibility to play a leading role 
in the analysis of the full Run-3 dataset, support of the CMS silicon pixel detector calibration 
and alignment, and engage in Phase-2 upgrade of the silicon pixel detector. The group is also 
involved in upgrade of the SpinQuest experiment with the target to search for dark matter and 
feasibility studies for future Higgs factories. 

The group of Prof. 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. The group's work 
includes analysis, software, and hardware efforts on campus. HAYSTAC is a 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.  CUORE, and the upcoming upgrade CUPID, are neutrinoless double-beta decay 
experiments which also search for a wide array of rare events, including symmetry violations and WIMP 
dark matter interactions. 

The group of Prof. Norcini develops instruments with exquisite sensitivity and background rejection 
capabilities for dark matter and neutrino experiments. The group is working with low-threshold, 
single-quanta skipper CCDs to directly detect dark matter. With the start of construction in 2024, 
our main focus is DAMIC-M, which will observe light dark matter-electron scattering for the first 
time or set world-leading limits in the sub-GeV mass regime. In parallel, we will also be involved 
with sensor R&D for the larger, lower background OSCURA experiment to be constructed in 2028 at SNOLAB. 
There are opportunities for fellows to lead various efforts within the projects, including CCD testing, 
underground detector construction, calibration studies, and physics analyses.
