President’s Message

On behalf of the American College of Toxicology and the ACT Council, it is my pleasure to invite you to attend the ACT 47th Annual Meeting, November 15–18, 2026, at the JW Marriott Hill Country in San Antonio, Texas.

ACT is a global community of professional scientists representing the pharmaceutical and biotech industries, regulatory agencies, contract research organizations, academia, and consulting firms. The mission of the College is to “Educate, Lead, and Serve” scientists by providing a forum to promote an exchange of information and perspectives on safety assessment and new developments related to applied toxicological sciences.

The Annual Meeting is the heart of ACT. Our November gathering brings together a community of toxicologists at venues conducive to idea exchange, professional networking, and continuing education. Our first-rate Scientific Sessions are member-driven and organized to maximize learning opportunities. The welcoming and collegial atmosphere of the Annual Meeting is a hallmark of ACT.

The 47th Annual Meeting will include a wide-ranging scientific program and educational courses, with distinguished plenary speakers, the popular Poster Session, an Awards Ceremony, and multiple professional networking events.

The ACT Expo and the ACT Annual Meeting Supporter Program provides companies with a unique environment to engage in networking and marketing opportunities with toxicologists, industry consultants, and other professionals. We invite your company to join us as an exhibitor or supporter so that you can make professional connections and gain valuable exposure at the Annual Meeting.

We invite you to join your professional friends and colleagues at the JW Marriott Hill Country in San Antonio to discover why the ACT Annual Meeting has become the preferred venue for practicing toxicologists.

Sincerely,
Patricia C. Ryan, PhD
2025–2026 President
