Dr. Valerian Kagan, professor and vice chair of the department of environmental and occupational health at the University of Pittsburgh Graduate School of Public Health has been awarded a Fulbright Scholar grant to serve as visiting research chair in science and the environment at McMaster University in Ontario, Canada, this fall. Dr. Kagan will use the time as a Fulbright Scholar to further his research developing substances that help cells repair and mitigate the effects of radiation after exposure to potentially lethal doses from incidents such as a “dirty” bomb detonation or nuclear power plant failure. The substances could also be useful in radiation therapy during cancer treatment.
