He had been a research assistant professor of environmental medicine at the University of Rochester. Dr. Laiosa’s research interests are focused on how environmental factors influence immunologically based human diseases, such as leukemia and autoimmunity. His specific interests involve identifying developmental and early-life environmental factors that influence cancer risks and autoimmune pathogenesis; identifying prenatal and early postnatal chemo-preventive agents that may reduce risk of such diseases as leukemia, atopy, and autoimmune disease; and determining the effect of early-life exposures to chemical mixtures on long-term immunologic health. Dr. Laiosa earned a PhD in microbiology and immunology from the State University of New York Upstate Medical University.
