Gain hands-on experience with the AOP wiki at SOT’s annual meeting

Headed to the Society of Toxicology’s upcoming meeting in San Antonio? The Human Toxicology Project Consortium and the Physicians Committee for Responsible Medicine invite you to deepen your understanding of the AOP Wiki and gain experience entering an Adverse Outcome Pathway in a structured, hands-on seminar Tuesday evening.
