    Overview
    overview
    Dr. Friedman's basic science research interests are in pro-hormone processing as related to drug addiction, diabetes, thyroid disease and obesity as well as substance abuse and the hypothalamic-pituitary-adrenal axis. He also is studying how glucocorticoids and enzymes that regulate their tissue levels are involved in diabetes and obesity. His clinical research interests are adrenal and pituitary disorders and he has an NIH-funded clinical trial giving testosterone to women with hypopituitarism. His clinic interests includes difficult to diagnose pituitary, adrenal and thyroid disorders. He is one of the world's experts on Cushing's syndrome. He also wrote a popular lay book on thyroid diseases.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
