EDOUARD I. AZZAM
Edouard I. Azzam is Professor in the Department of Radiology at Rutgers University - New Jersey Medical School. He received his doctoral degree in the field of radiation biology from the University of Ottawa (Canada) in 1995. From 1995 to 2000, he pursued post-doctoral studies at the Harvard School of Public Health under the mentorship of Professor John B. Little.

The outcome of these investigations may be significant towards reducing the uncertainty associated with current models for predicting the long-term health risks of exposure to radiation. His studies have been funded by the National Institutes of Health, the National Aeronautics and Space Administration, and the U.S. Department of Energy; and they have resulted in the training of numerous students and post-doctoral fellows who remain engaged in unraveling the biochemical events underlying the responses of human cells to ionizing radiation.
Jonine L. Bernstein
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.

Lydia B. Zablotska
is a Professor in the Department of Epidemiology and Biostatistics in the School of Medicine at the University of California, San Francisco (UCSF), where she serves as the Leader of the Occupational and Environmental Epidemiology Area of Concentration. Dr. Zablotska is a physician and epidemiologist with extensive training and publications in radiation epidemiology, biostatistics, and risk modeling. Her research activities have focused primarily on the examination of risks of radiation exposures in various occupational and environmental settings. Dr. Zablotska's work has clarified the understanding of the effects of occupational radiation exposures on health risks of nuclear power industry workers and workers of the uranium fuel production cycle in various occupational cohorts from the United States and Canada. As a Principal Investigator of the National Cancer Institute-funded Chernobyl studies, she published a number of important publications with the tri-national investigative team which showed that exposures to ingested and inhaled radioactive iodines during childhood lead to increased risks of thyroid cancer similar to risks from external radiation. Study findings redefined the emergency protocols for populations working or living around nuclear power plants and opened a new area of inquiry by showing that exposures to radioiodines increase not only the risks of thyroid cancer, but also of benign thyroid tumors such as follicular adenomas. Recently, the research conducted by Dr. Zablotska's research group showed that the cleanup workers of the Chernobyl nuclear accident are at increased risk of incident chronic lymphocytic leukemia and reported possible links with somatic point mutations related to telomere length maintenance. Dr. Zablotska serves as a Director of Epidemiology, Biostatistics and Population Health education in the medical school curriculum at UCSF and has received multiple institutional and national teaching and mentoring awards. She is the founder of the Early Stage Radiation Investigators Workshop conducted in conjunction with biennial meetings of the Conference on Radiation and Health.>/p>

Cary J. Zeitlin
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.
