began his professional career in radiation research in 1989 conducting experimental studies while a PhD student at the Southern Ural Biophysics Institute (SUBI). His thesis addressed cellular lung immunity after inhalation intake of Pu-239. Dr Sokolnikov joined the radiation epidemiology laboratory of SUBI in 1996 as a researcher, studying cancer effects following protracted occupational exposure to external gamma radiation combined with exposure to internally deposited alpha‐emitting Pu-239 among the cohort of Russian nuclear workers at the Mayak complex. The pattern of exposure in this cohort differs from that in atomic-bomb survivors by the type of radiation (external gamma exposure plus internal exposure to alpha particles) and the pattern of dose accumulation (chronic versus acute). Dr. Sokolnikov participated in a large‐scale study funded by Russian Federal Government together with governments or funding agencies from the European Union (EU) and the United States in 1996. In particular he participated in EU research program INCO‐Copernicus and EU research framework programs 6 and 7. Since 1996 he participated in research coordinated by Joint Coordinating Committee for Radiation Effects Research as a researcher and since 2006 as a Principal Investigator. In 2005, Dr. Sokolnikov became the Head of the Radiation Epidemiology Laboratory and in 2016 became the Head of the Epidemiology Division of Southern Urals Biophysics Institute. He was a member of the International Agency for Research on Cancer committee that prepared the recent monograph (Volume 100D) on effects of radiation exposure. In May 2017 he was elected as a member of International Commission on Radiological Protection Committee 1.

Dr. Story's research is funded by NCI, NASA, the Cancer Prevention and Research Institute of Texas, and industry.

He has been a member of a number of U.K., European Union, and international expert groups, including Committee 1 of the International Commission on Radiological Protection, the United Nations Scientific Committee on the Effects of Atomic Radiation, and the U.K. Committee on Medical Aspects of Radiation in the Environment. Following the 2011 Fukushima nuclear accident, he was a member of the U.K. Government’s Scientific Advice Group for Emergencies and the World Health Organization’s Health Risk Assessment Expert Working Group on the Fukushima accident.

holds a higher doctorate (DSc) in Radiation Epidemiology and PhD, MSc and BSc in Physics from the University of Manchester, United Kingdom. Her past work has included involvement with the World Health Organization expert group for assessing the radiation cancer risk in Japan after the 2011 nuclear accident at the Fukushima plant. Some highlights of Dr. Walsh’s research have included papers on analyses of: data from the Life Span Study cohort of Japanese survivors of the World War II atomic-bomb attacks; the development of epidemiological models for thyroid cancer risk in areas affected by the 1986 Chernobyl accident; and the mortality follow-up of German “Wismut” uranium miners. She is an Honorary Visiting Research Fellow in the Medical Physics Group at the University of Zurich, Switzerland and a freelance consultant based in Munich, Germany. She is currently involved as a partner, through the University of Zurich, in the European Union EU-CONFIDENCE (Coping with Uncertainty for Improved Modelling and Decision Making in Nuclear Emergencies) project, is a member of the International Commission on Radiological Protection Task Group 91, a member of the German Radiation Protection Commission Wismut steering committee, and a consultant to the European Space Agency.

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> Close
