Biographical Sketch: 

Bio: Professor Reina Maruyama is an experimental particle/atomic/nuclear physicist. She is exploring new physics in nuclear and particle astrophysics, in particular, in dark matter and neutrinos. Her group is carrying out experiments in direct detection of dark matter with terrestrial-based detectors for both axions and WIMPs and searches for neutrinoless double beta decay. The current experiments include COSINE-100, DM-Ice, IceCube, CUORE, and HAYSTAC.

Professor Maruyama graduated with a B.S. in Applied Physics from Columbia University. She obtained her Ph.D. in atomic physics for atom trapping and fundamental symmetries at the University of Washington. She was a Chancellor’s Postdoctoral Fellow at University of California, Berkeley and Lawrence Berkeley National Laboratory. She joined the faculty at UW-Madison in 2011, and subsequently Yale in 2013. 

She is an author of 200+ publications and has presented her work in numerous conferences and workshops. She is often quoted in popular science press such as APS News, Nature News, Science News, and Symmetry Magazine for her work on dark matter and neutrinoless double beta decay.


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

Honors & Awards: 

Maruyama is the recipient of several awards, including Sloan Research Fellowship, NSF CAREER Award, Yale Public Voices Fellowship, and Woman Physicist of the Month from CSWP.  She is a Fellow of the American Physical Society.
