Dr. Ahsan’s research interests focus on studying the inter-relationships between environmental and genomic factors in cancer and other diseases and exploiting information on these relationships at a population level in developing and evaluating prevention interventions in humans. Specifically, his research integrates the environmental, nutritional and life-style factors with measures of host factors and modern molecular genomics (involving DNA, RNA and protein variations) to understand the etiology, pathogenesis, prognosis and prevention of cancer and other disorders of national and international public health significance. He has published extensively on the molecular epidemiology and prevention of health effects of arsenic exposure and also on the molecular and genetic epidemiology of breast and other cancers.
