Towards Precision Toxicology

A new scientific approach

The aim of the international PrecisionTox project is to better protect the health of people and the environment by establishing New Approach Methodologies (NAMs) for chemical safety testing using a mix of genomics, metabolomics, evolutionary theory, quantitative genetics, data science, toxicology, and law. We use human cell lines and a diverse suite of well-established biomedical model organisms — fruit flies, water fleas, round worms, and embryos of frogs and zebrafish — as well as artificial intelligence (AI) approaches to uncover molecular toxicity pathways shared across the animal kingdom. The result is a new regulatory paradigm based on greater certainty at predicting which chemicals cause harm to humans without causing harm to other animals.

Pillars of the project


Replace traditional animal testing with an evolutionarily diverse suite of biomedical model organisms from multiple branches of the tree of life.

Variation in

Determine safe levels of exposure to chemicals based on genetic variation.


Collaborate with regulators and other key stakeholders in project planning, selection of chemicals for investigation, and case studies for applying Precision Toxicology in policy and law.
