The Program Planning Committee is pleased to present a varied scientific program emphasizing dialogue on a number of complex topics in toxicology. Bringing together scientists from industry, government, academia, and interest groups, the goal of the meeting is to build a better understanding through dialogue in a collegial and engaging environment for all participants.



Program Structure: After each presentation, there will be approximately 5-10 minutes for specific dialogue on the presentation such as clarifying questions regarding the content. Additionally, each session concludes with a moderated panel discussion that allows audience members and speakers alike to address the central questions of the session, address research gaps, and help advance science-based decision making.
