An elaborate system of transcription regulation is responsible for the morphological and behavioral complexity in higher eukaryotes. This regulatory system consists of diverse trans-acting protein factors and cis-acting regulatory DNA sequences. Recently, Chromatin ImmunoPrecipitation coupled with whole genome tiled microarray (ChIP-chip) and/or next-generation sequencing (Solexa, SOLid and 454) has evolved as a powerful and unbiased technique to study genome-wide in vivo binding of the trans-acting protein factors. The application of this technology to multiple factors and/or in multiple conditions allows biologists to study how trans-factors differentially regulate transcription in a combinatorial manner. However, it also poses great challenges for the development of effective algorithms, the key link between massive raw data and biological hypotheses.
. 12/2013: We received a 5-year NIH/NHGRI '''R01''' grant (scored at 6 percentile in its first submission) to study DNA Methylation


We developed a series of  algorithms to reliably detect and annotate ChIP-enriched regions using Affymetrix whole-genome tiling arrays, including 1) Model-based Analysis of Tiling-arrays (MAT; PNAS 2006) for ChIP-region detection, 2) extreme MApping of OligoNucleotide (xMAN, BMC Genomics 2007) for microarray probe mapping, 3) Cis-regulatory Element Annotation System (CEAS; NAR 2006) for ChIP-region annotation. Since the inception in early 2006, they have been adopted by hundreds of academic users and are now considered as the ChIP-chip data analysis standard in many labs. We are also working with the ENCODE spike-in consortium, which consists of more than 10 transcriptional regulation groups worldwide, to systematically analyze the performance variability introduced in ChIP-chip protocols, array platforms, and analysis methods.

Postdoctoral Fellowship:
We have developed a number of widely used algorithms to analyze next generation sequencing data from 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 >1600 citations since 2008.
