David R. Hamilton, PhD
David R. Hamilton acquired an honours degree in biological and medicinal chemistry, and a PhD in organic chemistry before working as a scientist in the pharmaceutical industry for several years. His research into the mind–body connection ultimately led him to leave that profession and become a motivational speaker. He went on to co-found an international relief charity, and he appears regularly in the media. He spends most of his time writing, giving talks, and leading workshops.
