The Speller Lab will be located on the Homewood Campus of Johns Hopkins University in the Bloomberg Center for Physics and Astronomy.  Our lab focuses on searches for rare events and new particles, particularly focusing on the search for neutrinoless double-beta decay and axion dark matter.

News & Announcements

Join the Search

If you’re interested in experimental searches for new physics, contact us! We’re looking for JHU graduate students to join our searches for dark matter and neutrinoless double beta decay. Contact Prof. Speller at danielle.speller@jhu.edu.

Postdoctoral Positions Available

We’re searching for a postdoc to join our searches for neutrinoless double-beta decay and axion dark matter. Details are available here: https://physics-astronomy.jhu.edu/about/jobs/ While the current ad is primarily targeted toward the search for neutrinoless double-beta decay, we are also interested in candidates to focus on the dark matter search. Please see the above link for […]

Lab Renovations!

We’re excited to be approaching the final draft stages of design for the Speller Lab renovation!  Once construction begins, the lab is anticipated to be completed in early Fall 2020.  

Searching for Neutrinoless Double-Beta Decay with CUORE

The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale bolometer experiment located deep underground in Laboratori Nazionali del Gran Sasso in Gran Sasso, Italy. CUORE is optimized to look for lepton number symmetry violation via the neutrinoless double-beta decay of 130Te. An observation of this decay would yield new insight into the nature of the neutrino mass, and possibly new clues into the origin of the observed matter-antimatter asymmetry in the universe.

Looking for Axion Dark Matter with the HAYSTAC Experiment

The Haloscope At Yale Sensitive to Axion CDM (Cold Dark Matter) is a tunable microwave cavity experiment at Yale University. HAYSTAC searches for axion dark matter from the galactic halo by looking for the conversion of axions to photons in the presence of a strong magnetic field.
