    Collapse Overview
    Following medical school, I completed my residency in pediatrics at Schneider Children's Hospital-Long Island Jewish Medical Center which is part of the Albert Einstein College of Medicine. I then completed a fellowship in pediatric hematology/oncology at Children's National Medical Center in Washington, DC which is part of the George Washington University School of Medicine. I then began my research career at the Children's Hospital of Orange County under the mentorship of Dr. Diane Nugent. There, I became interested in improving the treatment for patients with hemophilia and inhibitors and for children with blood clots. I received my first independent grants there inculding a grant from the FDA to study a new anticoagulant in children. In addition, I became interested in thromboelastography. In 2007, I moved the Children's Hospital Los Angeles where I am continuing to perform research in the same areas as I had started in Orange County.

    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.
