Humane Sciences and Toxicology Policy


The certificate program will introduce, and explain the application of, the “3Rs,” (reduction, replacement and refinement), which are the guiding principles of humane science as well as demonstrate how the use of humane science principles in biomedical research can lead to more robust scientific methodology and knowledge. The program's course of study covers the scientific principles needed to appreciate humane science and identify and evaluate its implications in biomedical research and public health policy. Persons completing the certificate program will be well equipped to translate new toxicological knowledge into scientifically credible product safety evaluations and hazard assessments and apply these concepts to environmental health decision making.

Educational Objectives

The educational objectives of this certificate program are:

  1. To provide students with an understanding of the principles that govern the relationship between biomedical researchers and laboratory animals;
  2. To demonstrate the application of transgenic, in-vitro, computational, non-mammalian and non-animal research in toxicology; and
  3. To illustrate the ways in which humane science and alternatives are used in setting regulatory standards and making environmental health policy decisions.


The certificate program is open to persons who hold undergraduate degrees from accredited colleges or universities, particularly in the fields of public health or the biomedical sciences. It is also open to any student in a graduate degree program at Johns Hopkins University. Persons who are members of Institutional Animal Care and Use Committees (IACUC) and/or involved in animal welfare issues are encouraged to participate in this certificate program.
