    A native of Los Angeles, Dr. LoPresti received both his medical degree and his Ph.D. in physiology from the University of Southern California. He first joined the Trojan family in 1974 as a biology undergraduate and finished his residency at the LAC+USC Medical Center ten years later. Dr. LoPresti has contributed to over fifty presentations, recently lecturing on a case of an aggressive Papillary Thyroid Cancer arising in the third trimester of pregnancy. In addition, he has had leadership roles in the American Thyroid Association and has been published in numerous journals, abstracts and book chapters.

    Altmetrics Details 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.
