A Genomic View of Epigenetic and Transcriptional Regulation

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.

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 Res 2011) using MNase-seq.
