Overview

Dr. Nicoloff's current research includes hormonal factors regulating human pituitary TSH release, mechanism of nonsuppressible thyroxine secretion, alternate routes of T4 and T3 metabolism, and significance of circulating serum thyroglobulin in the management of neoplastic and other thyroid disease states.

Dr. Nicoloff earned his medical degree from University of California, Los Angeles. Following his residency, he went on to complete a Metabolism Fellowship at University of Washington- Kings County Hospital.
