I have 30 years of experience and specialize in the field of clinical biochemistry with specific knowledge in the areas of biochemical endocrinology, breast cancer and thyroid disease. I have published on such topics as biomarkers for managing metabolic bone disease, the use of aromatase inhibitors for hormone dependent forms of breast cancer, and clinical guidelines for the use of thyroid function tests in patients with thyroid disease. I have testified on diagnostic test patents, physician malpractice and pharmaceutical company drug products.
