Director of Cancer Genomic Diagnostics
Children's Hospital of Philadelphia
Philadelphia, Pennsylvania, United States
Marilyn M. Li, M.D. is a Professor of Pathology and Laboratory Medicine, Professor of Pediatrics, Director of Cancer Genomic Diagnostics at Children’s Hospital of Philadelphia, University of Pennsylvania, Perelman School of Medicine. Dr. Li holds the American Board of Medical Genetics and Genomics certification in Clinical Cytogenetics and Clinical Molecular Genetics. She is a fellow of the American College of Medical Genetics (ACMG), Association for Molecular Pathology (AMP), American Society of Human Genetics (ASHG), American Association for Cancer Research (AACR), and American Society of Clinical Oncology (ASCO). She is the Chair of the AMP/ASCO/CAP Somatic Variant Interpretation Standards and Guidelines Working Group, and the co-chair of ClinGen Cancer Variant Interpretation Expert Panel. Dr. Li's primary research interest is the clinical application of advanced and high throughput multi-omics technologies in conjunction with modern bioinformatics tools in cancer research and clinical diagnosis to facilitate precision cancer care. Her group has studied thousands of cancers using multi-omics approaches including custom-designed cancer-specific microarrays, next-generation sequencing panels, and cancer exomes/genome/transcriptome/methylome/circulome sequencing. Their experience demonstrated that these state-of-the-art technologies uncover multi-dimensional alterations in cancer that are essential for cancer diagnosis, risk stratification, therapeutic selection, and prevention. She initiated, organized, and is the first president of the Cancer Genomics Consortium (CGC), an international consortium whose mission is to facilitate the development and utilization of cutting-edge technologies for high-quality, reliable cancer genetic testing in diagnostic laboratories. She is the recipient of the 2010-2011 Luminex/ACMGF Award for the promotion of safe and effective genetic testing and services, the Visionary Leadership Award of CGC in 2019, and the Excellence in Genetics Service Award by the Association of Chinese Geneticists in America in 2021. She has published over 120 peer-reviewed articles and has given more than 100 invited presentations and grand rounds nationally and worldwide.
