    Developing liquid biopsy tests for malignant effusions using artificial intelligence-assisted, morphology-based isolation of tumor cells
    NIH/NCI R01CA292019Aug 12, 2024 - Jul 31, 2029
    Role: Co-Investigator
    Description: The goal of this project is to validate an AI-assisted, morphology-based, label-free platform for enriching tumor cells from malignant effusions and develop liquid biopsy tools to evaluate breast cancer tumor biomarkers and identify drug targets.
    Race and ancestry as predictors of the tumor immune microenvironment and response to immunotherapy
    NIH/NCI P20CA290477Aug 1, 2024 - Jul 31, 2026
    Role: Co-Investigator
    Description: Using a combination of registry data, clinical trials data, matched gene expression and genotype data and single nuclear analysis, we investigate various ways that health disparities affect response to immune checkpoint inhibitors in breast cancer across populations.
    A systems biology approach to elucidate the biology of immune-associated outcomes in breast cancer
    NIH/NCI K01CA279498Aug 3, 2023 - Jul 31, 2028
    Role: Principal Investigator
    Description: The I-SPY 2 neoadjuvant breast cancer clinical trial is a personalized, adaptive trial designed to improve outcomes in high-risk breast cancer patients. This study seeks to develop computational and machine learning (ML) models to unravel the complex interactions between intrinsic host germline and tumor somatic mutations, and extrinsic tumor microenvironment features that drive the biology of response or resistance to therapy. Our study will leverage parallel transcriptomic, genomic, and fluorescence imaging data in the I-SPY2 trial to generate genomic and tumor microenvironment response-predictive biomarkers. Our study aims to improve on current qualifying biomarkers – providing better stratification of patients and directing them to best predicted interventions – and that identify possible alternative treatment strategies for non-responders – reducing unnecessary therapeutic burden.
    The I SPY 2.2 TRIAL: Evolving to Imaging and Molecular Biomarker Response Directed Adaptive Sequential Treatment to Optimize Breast Cancer Outcomes
    NIH/NCI P01CA210961Jul 3, 2023 - Jun 30, 2028
    Role: Co-Investigator
    Description: We have designed a clinical trial for women treated with drugs for early breast cancer before surgery, in which patients whose cancers do not respond to the initial experimental treatment can be switched to receive a different proven therapy that is considered the best for their particular type of cancer. Our goal is to develop a system that continuously improves our ability to provide each woman with the best chance at being cured, while also trying to avoid any unnecessary treatments that cause toxic side effects.

    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.
