Welcome, Dr. Oregui!

We are excited to welcome Dr. Beatriz Tapia Oregui, who will be joining us in the lab this fall as a 2022 William H. Miller Postdoctoral Fellow. Dr. Oregui completed her doctoral work this spring on NOvA at the University of Texas at Austin. Welcome, Beatriz!

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.
