Scientific Advisory Committee

The HRI Scientific Advisory Committee (SAC) is a team of independent world experts in homeopathy and Complementary and Alternative Medicine research, which provides the Institute with the strong scientific foundations essential to our work.

Members are appointed as independent scientific experts on the basis of their specific skills and knowledge. Individuals are required to declare any conflicts of interest.

As well as advising the charity on academic issues, SAC members provide a rigorous peer review process used to assess all incoming protocols, enabling us to confidently channel donations to the most promising research projects submitted to us.

The Committee enables HRI to operate with confidence, generating research of the highest quality and developing ever-stronger links throughout the international academic community.
