Peter Laird

Peter Laird is a leading authority on genome-wide DNA methylation profiling in cancer, having directed epigenomic analyses for The Cancer Genome Atlas (TCGA) consortium across dozens of tumor types. His laboratory defined CpG island methylator phenotypes across multiple cancers and developed computational methods for methylation-based molecular classification that have become standard in precision oncology. He has been instrumental in translating Illumina Infinium methylation array technology from research discovery to clinical diagnostic application, enabling methylation-based brain tumor classification systems now used worldwide.
