Research Interest
Dr. Challinor’s academic interests focus on improving the understanding and treatment of neuroendocrine and adrenal disorders. To address these complex problems, Dr. Challinor collaborates with members of the multidisciplinary neuroendocrinolology and adrenal centers which include neuroendocrinologists, neurosurgeons, otolaryngologists, endocrine surgeons, radiologists, radiation oncologists, opthalmolologists, and pathologists. Dr. Challinor’s scholarly work has included 1) analysis of outcomes following endonasal surgery for pituitary disease (i.e. Cushing’s disease, acromegaly, other pituitary tumors), 2) improving the use and diagnostic accuracy of bilateral adrenal venous sampling to distinguish among different causes of Cushing’s syndrome (i.e. ACTH-independent bilateral macronoduar adrenal hyperplasia versus unilateral functioning adenoma in patients with bilateral adrenal masses), and 3) characterizing genetic influences on the natural history and treatment of endocrine neoplasia. In addition to continuously improving the understanding and treatment of neuroendocrine and adrenal disorders, Dr. Challinor contributes to the education of medical trainees at all levels.
