Roles and responsibilities

Julie Leblanc is a radiation and health sciences officer at the Canadian Nuclear Safety Commission (CNSC). She provides technical support on behalf of and to the Commission on the subject of radiobiology and low dose radiation risk. She conducts and coordinates low dose radiation research and disseminates objective technical, scientific and regulatory information to the Canadian public, Indigenous groups and other stakeholders. She is also a member and strong supporter of the CNSC Women in STEM tiger team. Her role with COHERE is as a coordinator and researcher, and she is a member of both the COHERE Scientific Committee and the Communications Committee. She is also an International Commission on Radiological Protection mentee and a member of Task Group 111.
