    Collapse overview
    Dr. Romero is an Associate Professor in the Department of Obstetrics and Gynecology at the University of Chicago. Her research program focuses on identifying novel interventions for ovarian cancer prevention and treatment. To approach this her lab evaluates the cancer protective effects of medications that are widely used for non-cancer indications. Given the high cost and difficulty of new cancer drug development, drug repurposing or taping into the anti-carcinogenic potential of economical and widely used drugs is an important paradigm shift in cancer research. Her research program integrate of in vitro cancer biology techniques, mouse models of ovarian cancer and human clinical data and samples. Using this integrated approach, her group has reported anti-ovarian cancer effects of two commonly used medications: metformin used for diabetes and statins used for high cholesterol. Complementary to her research endeavors, Dr. Romero’s clinical practice provides comprehensive obstetrical and gynecological care to women at high risk for gynecologic malignancies, including those with a genetic predisposition to cancer.

    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.
