    Collapse overview
    I am an Assistant Professor of Clinical Population and Public Health Sciences in the Division of Biostatistics of the Department of Population and Public Health Sciences at the University of Southern California. I support the design, conduct, and analysis of pediatric cancer clinical trials of the Children's Oncology Group, where I focus on supportive care, survivorship, and cellular therapy trials. I also work on statistical methods for the evaluation of surrogate endpoints, focusing on Bayesian hierarchical modeling for meta-regression. Through my work in surrogate endpoints I collaborate with the Chronic Kidney Disease Epidemiology Collaboration.

    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.
