OAK RIDGE, Tenn.— The Radiation Emergency Assistance Center/Training Site (REAC/TS) in Oak Ridge, Tenn., welcomes three new team members: John Crapo, Josh Hayes and David Quillin.

John Crapo joins the team as a part-time health physicist after retiring from the National Nuclear Security Administration, where he served as a program manager in the Office of Nuclear Incident Response. Prior to that, Crapo spent nine years with Oak Ridge Associated Universities (ORAU) working on its flagship contract, the Oak Ridge Institute for Science and Education, serving as associate director for its national security programs. His experience also includes 26 years of active duty in the U.S. Navy, serving as a nuclear engineering technician and radiation specialist, retiring at the rank of lieutenant commander.

Crapo earned his bachelor’s degree in radiological health physics at the University of Massachusetts, Lowell; his master’s degree in health physics at Georgetown University; and a master’s degree in environmental health from the School of Public Health, Harvard University. Crapo is certified in the Comprehensive Practice of Health Physics by the American Board of Health Physics, serves as the president of Clarksburg Community Assistance Network and is the executive administrator at Cedarbrook Community Church, Clarksburg, Md.

Josh Hayes, Ph.D, joins the team as a health physicist. He served in the U.S. Marine Corps as a defense specialist and spent most of his enlistment stationed in Okinawa, Japan, where he was able to respond to the Fukushima nuclear disaster in 2011. That experience led Josh to pursue goals in studying radiological sciences.

Hayes holds a bachelor’s degree in biomedical sciences, a master’s degree in health physics and a doctorate degree in radiological health from Colorado State University (CSU). While working at CSU, he had the opportunity to travel several times for extended stays to Fukushima, Japan, to work with wildlife biologists and veterinarians, studying the impacts the environmentally dispersed radiation from the Fukushima nuclear disaster was having on wildlife. Specifically, he studied the hematological system of wild boar and field mice, which lead him to ORAU in 2018 for a summer internship. Following completion of his doctorate degree in 2020, Hayes moved to Vienna, Austria, to work for the International Atomic Energy Agency as a radiobiologist and biodosimetrist. In his spare time, he enjoys running the trails at Frozen Head State Park.

David Quillin comes to REAC/TS as a nurse. Most recently Quillin worked as an occupational health nurse at Oak Ridge National Laboratory. Prior to that, he worked as a critical care nurse at Fort Sanders Regional Medical Center while also working with the Knox County Sheriff’s Office as a reserve patrol officer. In addition to nursing, Quillin brings with him many years of law enforcement experience. He holds a bachelor’s degree in nursing from the University of Tennessee, Knoxville, and a master’s degree in business administration from the University of Kentucky.

OAK RIDGE, Tenn.— Dr. Mark Ervin has been named associate director of the Radiation Emergency Assistance Center/Training Site located in Oak Ridge, Tenn.

Ervin retired in 2020 as a colonel in the U.S. Air Force where he held numerous leadership and medical positions during his 25-plus year military career, including command surgeon, chief of clinical services and chief of operational medicine.

In his new position at REAC/TS, Ervin will provide management and medical leadership, participate in all aspects of emergency response planning, and manage all professional and technical activities of radiation emergency management at REAC/TS.

“We are thrilled to have someone with Dr. Ervin’s extensive background and proven track record joining REAC/TS,” said REAC/TS Director Carol Iddins. “Both his medical and leadership experience will help REAC/TS continue to serve as a world-renowned, U.S. Department of Energy asset and a leader in emergency medical response to radiological/nuclear incidents, providing emergency response and subject matter expertise on the medical management of radiation incidents for the National Nuclear Security Administration.”

Prior to joining REAC/TS, Ervin was responsible for oversight of 43 U.S. Air Force units that modernize and innovate advanced resuscitative, surgical and critical care wartime solutions for casualty and evacuation care from the point of injury on the battlefield to the care at U.S.-based military medical centers. He also was an Air Force subject matter expert on advancing autonomous patient care, evacuation on unmanned vehicles and severe-injury surgical teams supporting special operations. As a general surgeon, Ervin provided inpatient and outpatient surgical care at Wilford Hall Ambulatory Surgical Center and Brook Army Medical Center.

Ervin’s leadership and clinical experience comprise several headquarters positions in the Air Force and at U.S. European Command and Department of Defense Medical Centers, including a chief position at Landstuhl Regional Medical Center in Germany, where he participated in frequent flight missions in Europe and the Middle East, evacuating critically injured casualties.
