The Luc Morris Lab
Our laboratory works at the intersection of cancer genomics, molecular biology, animal models, and patient clinical data, to better understand how the genetic features of cancer cells lead to tumor development, evasion of the immune system, and aggressive tumor behavior. This multi-faceted approach can help us to discover new biomarkers and new genetic drivers. Our group has focused for many years on cancers of the head and neck (especially squamous cell, salivary and thyroid cancers). Using this approach, we have identified new cancer genes, developed new animal models, uncovered factors that cancers use to resist therapy or escape immune surveillance, and critically assessed genetic biomarkers that predict response to immunotherapy across multiple cancer types. Through these efforts, we hope to deepen our understanding of cancer genetics, and help set the stage for the next steps of rational clinical investigation informed by molecular insights.
