SOT Annual Meeting and ToxExpo 2026
The SOT 65th Annual Meeting and ToxExpo 2026 is taking place in San Diego between 22 and 25 March. If you are interested in meeting us there, we invite you to reach out to us via the form on this page.

Join Toxys Exhibitor Hosted Session!
NAMs and Their (Regulatory) Applications in Safety Testing
In this Exhibitor Hosted Session, we will present case-studies of NAMs for genetic-, developmental- and investigational toxicology and how they are used in regulatory or screening setting. We will highlight the regulatory acceptance of ToxTracker. Next, we will share updates for ReproTracker and have a panel discussion on setting up an in vitro strategy for DART testing and how to extrapolate data from in vitro to in vivo.
Where? San Diego Convention Center, Room 24A
Program:
- Updates on Toxys NAMs for genetic-, developmental- and investigational toxicology – Giel Hendriks, CEO at Toxys
- Gaining efficiencies in DART programs with ReproTracker – Pragati Coder, Global Lead (DART C&C) at Charles River
- Panel discussion on DART and the steps needed to move towards in vitro strategies with the following participants:
- Giel Hendriks, CEO at Toxys
- Pragati Coder, Global Lead (DART C&C) at Charles River
- Matthew Dent, Science Leader at Unilever
- Robert Landsiedel, VP at BASF Experimental Toxicology and Ecology
Please register for this on location event below. We look forward to meeting you in San Diego!
