The ASPIS cluster—comprising ONTOX, PrecisionTox, and RISK-HUNT3R—is gearing up for an exciting presence at the 2025 Society of Toxicology (SOT) Annual Meeting and ToxExpo in Orlando, Florida! From 17 to 20 March 2025, ASPIS experts will showcase cutting-edge advancements in non-animal methodologies (NAMs) and next-generation risk assessment (NGRA).
The ASPIS cluster is at the forefront of developing next-generation chemical risk assessment approaches that reduce reliance on animal testing. Presentations and posters of ASPIS researchers will cover the latest advancements in NAMs, computational toxicology, exposure science, and regulatory frameworks. Attendees are invited to visit exhibitors, attend insightful presentations, and engage with ASPIS researchers at poster sessions.
Exhibitors at the ToxExpo
- ASPIS Booth #1362 – Discover the latest developments from ONTOX, PrecisionTox, and RISK-HUNT3R.
- MN-AM Booth #530 – Meet ONTOX partner Jörg Marusczyk, the developer of the ONTOX Hub and marketplace.
