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

We have developed a number of widely used algorithms to analyze next generation sequencing data from ChIP-seq (MACS, MACE), 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 >1900 citations since 2008.  
 
In collaboration with experimental biologists, we used these algorithms to gain novel biological insights from various biological processes and disease models.

* '''DNA Methylation''': DNA methylation Canyon, Epigenetic changes in HSC aging, Dnmt3a in HSC differentiation and cancer transformation.  


We have developed a number of widely used algorithms to detect and annotate genome-wide cis-regulatory regions, including a Hidden Markov Model ('''Bioinformatics''' 2005) and MAT ('''PNAS''' 2006) for analyzing ChIP-chip experiments on genome tiling arrays, CEAS ('''NAR''' 2006) for cis-regulatory element annotation, xMAN ('''BMC Genomics''' 2008) for microarray probe mapping, MACS ('''Genome Biology''' 2008) for model based analysis of ChIP-seq, BSMAP ('''BMC Bioinformatics''' 2009) for DNA methylation analysis using Bisulfite-seq, MMES ('''PLoS ONE''' 2010) for alternative splicing using RNA-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 > 30 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 remodeling (Mnase-seq); 4) Alternative splicing (RNA-seq).
* '''Nucleosome Organization''': Fragile nucleosome in stress-response, Promoter nucleosome with Tup1, Nucleosome dynamics in ES differentiation, and Global nucleosome loss in yeast aging.


We have extensive experience in collaborative research, such as Estrogen Receptor regulation in breast cancer ('''Cell''' 2005; '''Nature Genetics''' 2006), Androgen Receptor regulation in prostate cancer ('''Molecular Cell''' 2007; '''Cell''' 2009), chromatin factor FoxA1 in epigenetic regulation ('''Cell''' 2008), Atoh1 in neuron development ('''PNAS''' 2011), fly transcriptome using RNA-seq ('''Genome Res''' 2011), and chimerical RNA biomarkers in prostate cancer ('''PNAS''' 2011). My laboratory also plays an important role in the BCM Epigenomics Data Analysis and Coordination Center for a five-year NIH Roadmap Epigenomics Program.
* '''Transcriptome''': chimeric RNA in prostate cancer, Long non-coding RNA in HSC, 3’UTR deletion in cancer and its master regulator CFIm25. .
