Our lab is focused on the design and application of bioinformatics algorithms to elucidate global epigenetic mechanisms and transcription dynamics in normal development and diseases such as cancer. Since establishing the lab in early 2008, we have published more than 50 peer-reviewed papers in high profile journals, such as Nature, Cell, Nature Genetics, Molecular Cell, Genome Research, Genome Biology, Genes and Development, Nucleic Acids Research, Cancer Research, PNAS and Bioinformatics. We developed a number of widely used algorithms to analyze next generation sequencing data from Chromatin Factor ChIP-seq (MACS, MACE, DyChIPS), DNA Methylation Bisulfite-seq (BSMAP/RRBSMAP, BSeQC, MOABS), Nucleosome Positioning MNase-seq (DANPOS), and RNA-seq (CPAT, RSeQC, DaPars). These algorithms have been broadly adopted by thousands of academic users. For example, the MACS algorithm has gathered >1000 citations since 2008. In collaboration with experimental biologists, we used these algorithms to gain novel biological insights from various biological processes and disease models. Chromatin Factors: ER in breast cancer, AR in prostate cancer, FoxA1 pioneer factor, Atoh1 in neuron development, NSD2 in oncogenic programming, SIRT7 in cancer transformation, ZM11 in transcription elongation, and p53 in ES differentiation. DNA Methylation: Dnmt3a in HSC differentiation, DNA methylation Canyon, HSC aging. Nucleosome Organization: fragile nucleosome in gene poising, promoter nucleosome with Tup1, nucleosome dynamics in ES differentiation, global nucleosome loss in aging. Transcriptome: chimeric RNA in prostate cancer, Long non-coding RNA in HSC, 3’UTR deletion in cancer and their master regulators. Lab Intranet openwetware
