Johns Hopkins Center for Alternatives to Animal Testing

**The Johns Hopkins Center for Alternatives to Animal Testing (CAAT), founded in 1981, is part of the Johns Hopkins University Bloomberg School of Public Health and Whiting School of Engineering.** We promote humane science by supporting creation, development, and validation of alternatives to animals in research, product safety testing, and education. We seek to effect change by working with industry, government, and academia to find new ways to replace animals with non-animal methods, reduce the number of animals necessary, or refine methods to make them less painful or stressful to the animals involved. CAAT is led by Director Thomas Hartung, Deputy Director Fenna Sillé, and Program Directors Lena Smirnova and Alexandra Maertens. CAAT-Europe, housed at the University of Konstanz, coordinates transatlantic activities to promote education in humane science. It also participates in, and coordinates, publicly and privately funded European projects. CAAT-Europe’s objectives include assembling a network of European experts and actively participating in the Transatlantic Think Tank for Toxicology (T4). It aims to coordinate knowledge exchange programs with the United States. It also works to set up international research consortia, support ALTEX as the official journal of CAAT, EUSAAT, and T4. CAAT-Europe collaborates with sponsors on strategic projects promoting humane science and innovative toxicology. Prof. Thomas Hartung is the program liaison representing Johns Hopkins, and Prof. Marcel Leist is the University of Konstanz liaison. Thomas Hartung is also a Professor of Pharmacology and Toxicology at Konstanz.
