The U.S. Environmental Protection Agency (EPA) will hold training on May 23, 2023, on Generalized Read-Across (GenRA), a publicly available tool that uses an automated approach to make reproducible read-across predictions of toxicity. EPA states that read-across “is a commonly used data gap filling technique whereby endpoint information for one substance is used to predict the same endpoint for another substance, supported by structural or other feature similarities.” According to EPA, while read-across sometimes relies on subjective or expert judgement, use of the GenRA tool could provide more objective and reproducible read-across predictions. Specifically targeted for decision-makers, this training will provide:
- A presentation overview of GenRA’s purpose and scope;
- A demonstration of GenRA’s interface and navigation; and
- Opportunities for participatory learning and engagement.
The virtual training will feature EPA’s Dr. Grace Patlewicz. The training will include a plenary presentation, small group discussions, and a chance to try out GenRA. EPA has divided the training into two parts to accommodate a variety of interests and schedules. Registration for one or both sessions is free but required.
- Session 1 (Presentation and Questions and Answers (Q&A)) 11:00 a.m. - 12:30 p.m. (EDT)
This session will provide an overview of GenRA content and function with opportunities for participation and Q&A.
- Session 2 (Breakout Sessions) 12:30 - 1:30 p.m. (EDT)
This session will break participants into breakout rooms to work on exercises in small groups, aided by facilitators.
