Research Interests
Our laboratory is focused on systems biology of human cancer, integrating high-throughput experimental platforms with large-scale computational genomics to address fundamental problems in the modern era of personalized or precision medicine. The lab seeks a systems-level understanding of the underlying genetic and epigenetic aberrations in cancer heterogeneity and immunity. We aim to identify novel biomarkers and drug targets, and to have a major impact on cancer by translating into more effective prognosis and therapy for human cancer.
