On April 27, 2017, Dr. Charles Geraci, Associate Director for Nanotechnology at the National Institute for Occupational Safety and Health (NIOSH), received the Director’s Distinguished Career Scientist Award. Dr. Geraci provides overall strategic guidance to the nanotechnology research program at NIOSH and is recognized internationally for his leadership in the field. Dr. Geraci has more than 40 years of industrial hygiene practice experience. He brings to NIOSH a unique blend of skills that he developed through his public and private sector professional practice. Dr. Geraci has made major contributions in the form of developing policy documents, refining research methods, developing field investigation strategies, and directly applying research outputs to effective worker health and safety approaches needed to develop emerging technologies responsibly. He serves as a subject matter expert on various national and international panels and advisory boards, including representing NIOSH on the U.S. National Nanotechnology Initiative and the Sub-Committee on Advanced Manufacturing. Dr. Geraci is also active on the International Organization for Standardization Technical Committee 229 on Nanotechnology, as well as the Organization for Economic Cooperation and Development (OECD) Working Party on Manufactured Nanomaterials, and serves on the executive committee of the American Industrial Hygiene Association Nanotechnology Working Group. Speaking for all in the nano community, the honor is richly deserved as Dr. Geraci’s service to the community and his scholarship and leadership are without equal.
