Biographical Sketch: 

Reina Maruyama is a professor of physics at Yale University. Her research focuses on the study of neutrinos and fundamental symmetries, astrophysics & cosmology, elementary particles, quantum science, and sensing; with particular focus on understanding the particle nature of dark matter and neutrinos and the role of symmetry in fundamental physics.

Before joining the faculty at Yale University, she was on the faculty at the University of Wisconsin and a postdoctoral researcher at the University of California-Berkeley.

Professor Maruyama received her Bachelor of Science degree in Applied Physics from Columbia University, and Masters and Ph.D. in Physics from The University of Washington. Her thesis work was Optical Trapping of Ytterbium Atoms

Research:

Reina Maruyama develops technologies and carries out experiments to probe the underlying physics of fundamental symmetries, origins of the Universe, and nature of neutrinos and dark matter. The Maruyama group uses techniques being developed in the fields of quantum sensors, atomic, nuclear, particle, and astrophysics to solve some of the greatest mysteries of the evolution of the Universe.

Education:

Ph.D., University of Washington, Seattle, 2003

Honors & Awards:
Maruyama is an American Physical Society (APS) Fellow and a member of the Connecticut Academy of Science and Engineering (CASE). She was awarded the Sloan Research Fellowship, NSF CAREER Award, Yale Junior Faculty Fellowship, Yale Public Voices Fellowship, the APS Committee on the Status of Women in Physics Woman Physicist of the Month (June 2013) and held a Chancellor’s Postdoctoral Fellowship at the University of California-Berkeley. Maruyama was featured in Ingenium’s Women in STEM initiative and is the co-leader of Yale’s Asian Americans in STEM initiative.

COSINE-100

Maruyama

Science goal: Search for direct detection of dark matter, probing for an annual modulation in the signal reported by the DAMA/ LIBRA collaboration.

WL involvement: Maruyama is the PI and scientific co-spokesperson of COSINE-100.

CUORE & CUPID

Heeger, Maruyama

Science goal: Search for neutrinoless double beta decay, which could answer why we live in a Universe of matter, not antimatter.

WL involvement: Yale is responsible for detector calibration, the study of cosmogenic backgrounds, double beta decay analysis, & the search for solar axions. Heeger and Maruyama are CO-PIs of CUORE & CUPID.

IceCube

Maruyama

Science goal: Search for neutrinos by studying exploding stars, gamma-ray bursts, black holes, and neutron stars.

WL involvement: The Maruyama group studies how supernovae explode, as well as fundamental properties of neutrinos.
