Danielle Speller is a researcher in experimental nuclear and particle astrophysics.  Her work centers on understanding the nature of matter and mass through low-energy, cryogenic searches for physics beyond the standard model. Professor Speller is a collaborator on both the Cryogenic Underground Observatory for Rare Events (CUORE) and the Haloscope at Yale Sensitive to Axion Cold dark matter (HAYSTAC), as well as related R&D projects.  Her graduate work was with the Super Cryogenic Dark Matter Search experiment (SuperCDMS).

Professor Speller was a Park Scholar at North Carolina State University in Raleigh, North Carolina, and graduated with a double-major in physics and applied mathematics.  She earned her Ph.D. from the University of California, Berkeley, and joined the Maruyama Lab at Yale University’s Wright Laboratory in 2017 as a Postdoctoral Associate.  She joined the Physics Department in July 2020 as an Assistant Professor of Physics.
