Our lab is focused on the design and application of bioinformatics algorithms to elucidate global regulatory mechanism by integrating data from ChIP-seq, DNA methylation, Nucleosome positioning, and RNA-seq. We are also working with bench and clinical collaborators to understand epigenetic gene regulation and transcription dynamics in various biological processes and disease models.  
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.  


We have developed a number of widely used algorithms to detect and annotate genome-wide cis-regulatory regions, including MAT ('''PNAS''' 2006) for analyzing ChIP-chip experiments on genome tiling arrays, MACS ('''Genome Biology''' 2008) for model based analysis of ChIP-seq, BSMAP/RRBSMAP ('''BMC Bioinformatics''' 2009; '''Bioinformatics''' 2012) for DNA methylation analysis using Bisulfite-seq, and fragile nucleosomes ('''Genome Re'''s 2011) using MNase-seq. These algorithms have gathered thousands of academic users worldwide and hundreds of citations, including > 50 papers in Cell and Nature series. We are currently working on bioinformatics development for 1) Transcription factor binding and histone modifications (ChIP-seq); 2) DNA methylation at single nucleotide resolution (Bisulfite-seq); 3) Nucleosome dynamics (Mnase-seq); 4) Alternative splicing (RNA-seq).
* Nucleosome Organization: fragile nucleosome in gene poising, promoter nucleosome with Tup1, nucleosome dynamics in ES differentiation, global nucleosome loss in aging.


We have extensive experience in collaborative research including androgen and estrogen receptors in prostate and breast cancers ('''Cell''' 2005; '''Nature Genetics''' 2006; '''Molecular Cell''' 2007; '''Cell''' 2009), epigenetic regulation by histone modifications ('''Cell''' 2008; '''PNAS''' 2011; '''Cancer Res.''' 2011; '''Molecular Cell''' 2011; '''Nature''' 2012), nucleosome positioning ('''Genome Res.''' 2011), DNA methylation ('''Nature Genetics''' 2012) and novel chimerical RNAs in prostate cancer ('''PNAS''' 2011).
* Transcriptome: chimeric RNA in prostate cancer, Long non-coding RNA in HSC, 3’UTR deletion in cancer and their master regulators.
