| Lydia Zablotska's research activities have focused primarily on the study of the effects of radiation exposures, and on nutritional epidemiology, particularly as it relates to cancer risk. She is currently the principal investigator in a NCI-funded contract which provides scientific support for three studies of the consequences of the Chornobyl accident . Two cohort studies of thyroid cancer and other thyroid diseases are being conducted among more than 25,000 exposed as young people to fallout from the accident, where the focus is on the relationship between exposure to radioactive iodines and an increased risk of thyroid cancer and other thyroid diseases. The third study is a case-control study of leukemia in Chornobyl clean-up workers from Ukraine.
Dr. Zablotska is acting as principal investigator of the analysis of mortality in relation to occupation radiation exposures among employees of the Atomic Energy of Canada Ltd (AECL). Other radiation-exposed cohorts with which Dr. Zablotska is currently involved include those of uranium miners and processors in Canada, and Canadian tuberculosis patients exposed to repeated chest fluoroscopies in the 1930s and 1940s. Most recently, Dr.Zablotska has collaborated on an EPA-funded cohort study investigating carcinogenic effects of arsenic exposure among 12,000 adults in Bangladesh, analyzing the modifying effects of nutrition on the association between exposure to water arsenic and skin lesions.
In addition to her research activities, Dr. Zablotska directs the largest introductory class in epidemiology, P6400 Principles of Epidemiology and continues to teach an advanced research methods seminar for doctoral students in the Department of Epidemiology. She is the author of Epiville, an open-access website featuring a set of interactive modules providing training in main epidemiological principles (http://www. ccnmtl.columbia.edu/projects/epiville/).
