Lynn L. Bergeson will speak at a May 8, 2013, conference on recent advances in environmental health and safety (EHS) of engineered nanomaterials. The University of California Center for Environmental Implications of Nanotechnology (UC CEIN) is holding the conference on “Scientific Advances Towards Reducing Complexity in Decision Making.” Participants will include industry, regulators, policy makers, nano EHS professionals, and academics from the State of California, nationally, and internationally. The focus of the conference will be on developing alternative testing strategies for engineered nanomaterials and how engineered nanomaterials can be used for decision making in industrial, regulatory, policy, and academic settings. Participants will discuss how the advancement of environmental nanotechnology research impacts daily operations and decision making processes. The National Science Foundation (NSF) and the U.S. Environmental Protection Agency (EPA) are funding the conference. The conference is free, but registration is required.
