Mission & Focus Areas

SOT states that its mission is “to promote the acquisition and utilization of knowledge in toxicology and to facilitate the exchange of information among its members as well as among investigators of other scientific disciplines.” Its 2024–2027 strategic plan prioritizes scientific excellence, communication of scientific advances, development of toxicologists, and a welcoming, diverse, inclusive culture.

SOT’s funding includes student internship-fellowships, travel and trainee awards, and research support. For example, its Colgate-Palmolive Grant for Alternative Research supports projects to promote, develop, refine, or validate scientifically acceptable alternatives to animal methods for chemical and formulation safety assessment. SOT’s Global Initiatives Funding supports eligible meetings or programs relevant to its strategic vision.

The 2025 recipients illustrate several types of organizations supported. The University of Louisville Research Foundation says it promotes and supports research projects, investigations, clinical services, and other activities related to the university’s missions. The University of Kansas Medical Center Research Institute says it promotes and aids the medical center’s research, educational, and service functions. King University describes its mission as preparing students to serve as thoughtful, resourceful, and responsible citizens. Research Triangle Institute says it aims to improve the human condition by turning knowledge into practice.

Grantmaking

In filing year 2025, SOT reported 11 grants totaling $138,827. Grant amounts ranged from $8,000 to $33,000, with a median of $12,000. The stated purpose for the listed grants was student internship-fellowship.

The largest grant was $33,000 to the University of Louisville. Other notable grants were $12,494 to Rutgers the State University of New Jersey; $12,333 to the International Union of Toxicology; $12,000 each to King University, the Trustees of Purdue University, and the University of Kansas Medical Center Research Institute; and $11,000 to Research Triangle Institute International.

SOT also offers award programs for scientists and trainees. The IRSS Outstanding Postdoctoral Trainee Award, for example, provides a $500 cash award to recognize contributions in inhalation or respiratory toxicology. The NCAC-SOT Fall Symposium Trainee Abstract Award offers $100 or $200 to eligible trainees presenting research at the chapter symposium.

For Global Initiatives Funding, applications are reviewed quarterly. Applicants are asked to provide meeting or program details, an organizing committee roster, an itinerary and speaker list, a rationale identifying beneficiaries, and an itemized budget. The request must also explain, in no more than 250 words, the meeting’s relevance to SOT’s strategic vision. Funding is typically $500–$4,000.

The Colgate-Palmolive Grant for Alternative Research offers a maximum cash award of $40,000. Applicants may be at any career stage and do not have to be SOT members when applying, but a selected nonmember must apply for membership. The application calls for a face page, a proposal including an abstract and research plan, a CV, and a signed institutional letter attesting to laboratory access. Evaluation considers applicant capacity, research implications, scientific and technical merit, and budget.
