Summary of research interest:
Although skin is the largest organ in the body, the role of thyroid hormone metabolism in epidermal proliferation has not been investigated with rigor. In the thyroid research unit we endeavor to establish mechanistic pathways integral to thyroid hormone action on adult skin. The research attempts to provide possible therapeutic targets for enhancing or suppressing the proliferative response of skin in such diverse conditions as psoriasis, burn injury, and wound healing. The laboratory has been developing a research program to demonstrate that local manipulation of thyroid hormone economy would prove a novel and cost-effective strategy for the treatment of cutaneous pathology.
