Dr. Pacak is an international expert on pheochromocytoma/paraganglioma and has put together this research protocol at the NIH. He is currently working as the Chief of Section on Medical Neuroendocrinology, NICHD. He has been at the NIH for over 15 years and has published numerous of articles, spoken at many lectures and contributed to numerous books on this topic. He and his colleagues have developed new biochemical and imaging approaches for localizing pheochromocytoma and paraganglioma tumors.
