Since finishing training at the University of Colorado Health Sciences Center in 1993, Dr. Haugen has been interested in the molecular mechanisms governing thyrotrope function and thyroid neoplasms. His current clinical interests include thyroid neoplasms, advanced thyroid cancer, thyroid dysfunction and other endocrine tumors (parathyroid, adrenal, carcinoid). Dr Haugen’s research interests include molecular studies of thyroid neoplasm diagnosis and pathophysiology as well as the study of molecular therapeutic targets. Specific areas of research include nuclear hormone receptors (RXR, TR, PPAR) and kinase signaling pathways as therapeutic targets in thyroid cancer, as well as proteomic approaches to molecular markers in thyroid neoplasms. His research group is also actively studying novel regulation of the hypothalamic-pituitary-thyroid axis.
