Ray Bunker is a physicist in the Radiation Detection and Nuclear Science group within the National Security Directorate.

Prior to joining PNNL in September 2015, he was a Research Scientist at the South Dakota School of Mines & Technology, contributing to both SuperCDMS and LZ. Dr. Bunker was the Analysis Coordinator for the SuperCDMS Collaboration for two years and is currently the chair of the Backgrounds Working Group and the Level-3 manager of the Radon Exclusion subsystem for the SuperCDMS SNOLAB project. He is also a contributing member of the Materials and Assay Working Groups for the LZ and DarkSide-20k projects.

Dr. Bunker began working in the dark matter field as an undergraduate at MIT where he contributed to the Axion Dark Matter Experiment. He studied dark matter in graduate school and wrote his dissertation on the first low-threshold search for dark matter using CDMS detectors. Dr. Bunker continued dark-matter investigations at Syracuse University as a post-doc working on both the SuperCDMS Soudan and MiniCLEAN experiments, while also acquiring expertise in radon mitigation and detection.

Dr. Bunker received his B.S. in Mathematics from MIT in 1997 and his Ph.D. in Physics from UC Santa Barbara in 2011.
