Formby began his career at the Sansum Medical Research Institute in the early 1980s, where he concentrated on biochemical models of insulin resistance in diabetes, and also looked at hormone receptors in cancer animal models. His work in diabetes covered receptor sites for specific insulin molecules, and in cancer research, he was involved with some of initial research in estrogen-receptor hormones, which led the way for the use of specific types of therapies such as Tamoxifen. He is considered^{[by whom?]} one of the world's authorities on environmental aspects as they relate to hormone reactions.
