directed Landauer's technical activities relating to radiation dosimetry, particularly for applications in radiation protection from 1983 through his retirement in 2015. Additionally, he oversaw subsidiary and partner businesses located in Australia, Brazil, China, France, Mexico, Japan, Sweden and Turkey.

An internationally known expert in radiation monitoring, Dr. Yoder led Landauer's transition from film and thermoluminescent dosimetry technology to optically stimulated luminescence, an assignment that required strategic planning and direction in areas spanning scientific research, product development, manufacturing, laboratory operations and marketing. From 1993 to 2001, he was Vice President of Operations and managed Landauer's manufacturing and analytical laboratory activities in addition to overseeing research and development programs.

Dr. Yoder is a member of NCRP and former President of the Council on Ionizing Radiation Measurements and Standards. He has served on several national and international committees to develop dosimetry standards. He was a member of a National Research Council committee that examined the accuracy of film badge measurements made during atmospheric nuclear weapons testing.

Dr. Yoder earned his MS and PhD degrees in Bionucleonics at Purdue University and received a BS in Pre-Medicine from Davidson College. He also completed the Executive Program at Stanford University. He is Certified in Comprehensive Health Physics by the American Board of Health Physics.

is a Senior Research Scientist with Leidos Innovations Corporation, working for the National Aeronautics and Space Administration (NASA) Johnson Space Center Space Radiation Analysis Group to assess exposures and risks to astronauts in current and future mission scenarios. He began his career in particle physics in the early 1980s, scanning nuclear emulsion that had been exposed to a beam of high-energy iron ions at the Lawrence Berkeley Laboratory (LBL) Bevalac. As this is one of the most tedious jobs imaginable, greener pastures soon beckoned, leading him to join the TPC/Two-Gamma Collaboration at the Stanford Linear Accelerator Center. After receiving his PhD in experimental high-energy physics and spending another 3 y at the Stanford Linear Accelerator Center as a postdoc studying the decays of the Z boson, Dr. Zeitlin returned to LBL and to nuclear physics in 1991 to work on a long-term project measuring the fragmentation cross sections most pertinent to NASA’s space radiation transport codes. This experience led to his taking over as Principal Investigator of the Martian Radiation Environment Experiment (MARIE) aboard the Mars Odyssey orbiter following the untimely passing of Dr. Gautam Badhwar. This led subsequently to his role as Co-Investigator with the Radiation Assessment Detector (RAD) project starting in 2008, as the instrument was being prepared for integration into the Curiosity Rover. After the successful transit and spectacular landing of Curiosity on Mars in 2012, RAD has been operating almost without interruption on the surface, sending back the first detailed radiation environment measurements from another planet. A second RAD was built for the International Space Station and began flight operations in early 2016. Dr. Zeitlin has received two Outstanding Performance awards from LBL and has received three awards from NASA for his work on the MARIE, RAD, and CRaTER projects. He was elected to the NCRP in 2014.

is an Attending Epidemiologist at the Memorial Sloan-Kettering Cancer Center (MSKCC) in New York City. Her core research focus is on breast cancer and gliomas and on understanding cancer risk and progression in order to identify those at highest risk because of gene carrier status, environmental exposures, or a combination of both. Dr. Bernstein is the Principle Investigator of the National Cancer Institute (NCI)-funded international 24-center Women's Environmental Cancer Radiation and Epidemiologic (WECARE) Study which was specifically designed to examine the interaction of radiation exposure and genetic predisposition in breast cancer, especially radiation-associated contralateral breast cancer (CBC) among 3,700 women with CBC and unilateral breast cancer. The WECARE Study has served as the source population for studies of candidate genes such as BRCA1, BRCA2, CHEK2, and ATM, candidate gene pathways of DNA damage response involved in radiation-induced double-strand break repair—ATM, CHEK2, P53 binding protein (53BPI), and MDC1, Mre11, Rad50, and Nbs1 (e.g., MRN nuclease complex), a genome-wide association study, and most recently mammographic density. The global hypothesis across these studies is that women who carry certain types of mutations will be more susceptible to breast cancer than noncarriers, and possibly to radiation-associated breast cancer.

Dr. Bernstein currently serves as a member of the Board of Directors of the American College of Epidemiology, the External Advisory group for the NCI-sponsored Breast Cancer Family Registry, the National Council on Radiation Protection and Measurements, and most recently the NCI Board of Scientific Counselors-Clinical Sciences and Epidemiology. For the past two years, she has served on the Organizing Committee of the American Statistical Association Conference on Radiation and Health (2012 and 2014 meetings), and was Co-Chair of the Third North American Congress of Epidemiology, held in June 2011 for which she was honored by the 2012 ACE Award for Leadership and Service in Epidemiology. Dr. Bernstein holds a PhD in Epidemiology from Yale University, an MS in Applied Biometry from the University of Southern California, and an AB from Brown University. Before joining the faculty at MSKCC, she was Deputy Director of the Division of Epidemiology at Mount Sinai School of Medicine.

He has a BS in Biology and MS in Public Health from the University of North Carolina at Chapel Hill.

is Professor of Radiology at the University of California (UC) Davis School of Medicine in Sacramento, California. He received a PhD in Radiological Sciences from UC Irvine in 1982, specializing in quantitative digital fluoroscopic imaging. Directly thereafter, he took a faculty position at UC Davis Medical Center, pursuing digital imaging research, physics education efforts for graduate students and radiology residents, as well as quality control for medical imaging equipment in Diagnostic Radiology. He has continuing academic interests in digital mammography, computed tomography, interventional radiology, imaging informatics, and radiation dose tracking, assessment, and reporting. Former president of the American Association of Physicists in Medicine (AAPM) in 2011 and current Governor of the American Board of Radiology, Dr. Seibert has served and continues to interact with many professional committees in regards to medical imaging issues and presenting technical / educational events for the AAPM, International Atomic Energy Agency, and other professional societies. For NCRP, he is a member of Program Area Committee 4.
