Dr. Jane Bayani
Co-Director, Diagnostic Development
Dr. Bayani’s research focus is on precision medicine approaches to discover and validate biomarkers using large, well-annotated retrospective clinical and clinical trial cohorts.
Translation of biomarkers and their diagnostic platforms are key to prospective clinical trial design and successful uptake in the diagnostic setting. Critical to understanding the variable outcomes seen in the current standard of care treatment for cancers like breast and prostate is recognizing the impact of genomic heterogeneity and serves as models for discovery and translational initiatives in other cancer types. Specifically Dr. Bayani’s team investigates the impact of heterogeneity at the genomic, transcriptomic, and proteomic levels and their integration with other diagnostic testing modalities such as imaging and digital pathology to build a clinical toolbox that can to improve risk assessment and treatment decision-making. This can significantly reduce the unnecessary overtreatment of some patients, while accelerating it in others.
