UL Research Institutes’ Chemical Insights’ scientists will share findings from their safety science research portfolio across more than 16 presentations, sessions and events during the Society of Toxicology’s (SOT) 65th Annual Meeting and ToxExpo this week in San Diego.

The SOT Annual Meeting convenes more than 4,000 scientists and research professionals to explore advances in toxicology and emerging technologies, while offering networking and mentoring opportunities. The three-day ToxExpo features more than 275 exhibitors connecting toxicologists with tools, services and potential partners, and the annual meeting includes 1,900 scientific presentations and more than 50 scientific sessions.

“Our team is focused on generating practical, decision-ready evidence about chemical exposures and health risks,” said Russell Thomas, Ph.D., Vice President and Executive Director of Chemical Insights. “At SOT, we’re sharing new methods and findings that help the field move toward faster, more transparent science to protect people and communities.”

About UL Research Institutes’ Chemical Insights

UL Research Institutes’ Chemical Insights conducts scientific research on chemicals and their risks to people’s health. Through open science, education, and collaboration, we provide trusted toxicity and exposure information to help regulatory agencies, companies, educators, and communities make informed decisions that protect public health.

About UL Research Institutes

UL Research Institutes is an independent, nonprofit organization advancing public safety through scientific discovery. Since 1894, we’ve worked to build a safer, more secure, and sustainable future. Our researchers investigate critical risks — from fire safety and chemicals to energy storage, digital privacy, and emerging materials — through rigorous, unbiased science. We collaborate globally and share our findings openly to inform standards, policy, and public understanding, while also cultivating the next generation of safety scientists through innovative educational programs and research experiences. As part of a broader safety ecosystem, we operate independently from UL Standards & Engagement and UL Solutions, while contributing to a shared mission: working for a safer world.
