SALLY A. AMUNDSON
is an associate professor of radiation oncology in the Center for Radiological Research at the Columbia University Medical Center in New York. She holds a doctorate in radiation biology and cancer biology from the Harvard School of Public Health. Her research uses functional genomics approaches to study low dose radiation and bystander effects, unique effects of space radiation, and the development of gene expression approaches for radiation biodosimetry.
She is co-director of the Center for High-Throughput Minimally-Invasive Radiation Biodosimetry. Prior to joining the group at Columbia, Dr. Amundson worked on molecular radiation biology in the Division of Basic Science at the National Cancer Institute (NCI), where she helped to develop global gene expression profiling techniques, and where she was an adjunct investigator in the NCI Radiation Epidemiology Branch. She has served on the NCRP since 2004 and on the Science Advisory Committee of the Radiation Effects Research Foundation (RERF) in Hiroshima since 2009, chairing the RERF scientific review for 2012.
Dr. Amundson is an associate editor of Radiation Research, and has served on the organizing and program committees for numerous meetings, including two of the American Statistical Association Conferences on Radiation and Health, which aim to integrate radiation biology with epidemiology. She is a recipient of the Michael Fry Research Award from the Radiation Research Society (RRS), and she is also a member of the RRS Council.
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.
RAYMOND A GUILMETTE
received a BS in nuclear engineering from Rensselaer Polytechnic Institute and an MS in environmental health sciences and a PhD in radiological health from New York University. For almost 40 y, he has been studying the metabolism, biokinetics, dosimetry, biological effects of internally deposited radionuclides, developing methods for removing radionuclides from the body (decorporation), and studying the mechanisms of deposition, clearance and retention of inhaled materials. Most of this research was performed at the Lovelace Respiratory Research Institute (LRRI) (formerly the Inhalation Toxicology Research Institute), where he worked for 23 y. From 2000 through 2007, he was team leader for internal dosimetry at the Los Alamos National Laboratory, assessing radiation doses for workers who were exposed to radionuclides associated with the nuclear weapons industry.
In 2007, he returned to LRRI as director of the Center for Countermeasures Against Radiation where he evaluated the efficacy of chemical compounds designed to decorporate radionuclides as well as drugs designed to ameliorate the effects of acute radiation syndrome from large external radiation doses in small and large animal models. He is a past president of the Health Physics Society, received its Distinguished Scientific Achievement Award in 2002, and has given several honorary lectures (Newell Stannard Memorial Lecture, 2006; G. William Morgan Lecture, HPS, 2009; inaugural Patricia W. Durbin Memorial Lecture, Lawrence Berkeley National Laboratory, 2010). He is a member of scientific committees of the International Commission on Radiological Protection, NCRP (a past board member), the International Agency for Research on Cancer, U.S. Environmental Protection Agency, and the U.S. National Academies of Science.
is a staff biophysicist at the Lawrence Berkeley National Laboratory (LBNL). Her research focuses on fundamental processes that may result in genomic change following exposure to sparsely or densely ionizing radiation. Her group has also addressed links between molecular mechanisms of DNA damage repair and programmed cell death. Dr. Kronenberg teaches radiation biophysics to students at the National Aeronautics and Space Administration Space Radiation Summer School. Dr. Kronenberg received her ScD in Cancer Biology from the Harvard School of Public Health. She has served on review panels for federal agencies and international scientific review panels. She is a senior editor for Radiation Research and is also a member of the editorial board of the Journal of Radiation Research (Japan). Dr. Kronenberg's activities with NCRP have included prior service on the Board of Directors, as a member or chair of the Nominating Committee, and as a member of several scientific committees. She was recently an invited speaker at the 2011 Annual Meeting and is currently a member of NCRP Program Area Committee 1.
DANIEL O. STRAM
is Professor in the Department of Preventive Medicine at the Keck School of Medicine of the University of Southern California. He received his PhD in statistics from Temple University in 1983 and served as a postdoctoral fellow in the Biostatistics Department of the Harvard School of Public Health from 1984 to 1986. From 1986 to 1989 he was a research associate at the Radiation Effects Research Foundation in Hiroshima, Japan.
Dr. Stram's main areas of research are in the statistical problems that arise in the design, analysis and interpretation of epidemiological studies of cancer and other diseases. His work on radiation epidemiology studies includes: (1) helping to characterize the statistical nature of errors in dose estimates for the atomic-bomb survivor study, (2) developing a multi-level variance components model for the dosimetry used in the Colorado Plateau uranium miners cohort for the purpose of better understanding dose and dose-rate effects in those data, and (3) characterizing study power and sample size issues in epidemiologic studies in which a complex dosimetry system is used to estimate radiation dose. Besides the field of radiation epidemiology his past and current research has focused on statistical issues relevant to clinical trials of treatment for pediatric cancer, nutritional epidemiology studies, and to studies of the genetics of complex diseases. He is an elected fellow of the American Statistical Association and has authored or co-authored over 200 peer reviewed articles.
