                <p>X. Shirley Liu received a PhD in Biomedical Informatics and a PhD minor in Computer Science from Stanford University in 2002.
                    She is a Professor with the Department of Biostatistics and Computational Biology at the Dana-Farber Cancer Institute and Harvard School of Public Health.
                    Shirley is a computational biologist with expertise in cancer epigenetics.
                    Her research focuses on algorithm development and integrative mining from big data generated on microarrays, massively parallel sequencing, and other high throughput techniques to model the specificity and function of transcription factors, chromatin regulators and lncRNAs in tumor development, progression, drug response and resistance.

        <h2>Research interests</h2>
        <p>Our research focuses on algorithm development and integrative mining from high throughput data to understand gene regulation in cancer biology.
            We have developed a number of widely used algorithms for transcription factor motif finding, ChIP-chip / ChIP-seq / DNase-seq / CRISPR screen data analysis.
            Through integrating genome-wide transcription factor binding, chromatin dynamics, gene expression profiles, and chemical and functional screens, we try to model the specificity and function of transcription factors, chromatin regulators, RNA binding proteins, kinases, and lncRNAs in tumor development, progression, drug response and resistance.

            <p>We have been developing algorithms (MACS, Cistrome, NPS, BETA) to facilitate the analysis of epigenomic data and use integrative modeling approaches to study genomic transcriptional and epigenetic gene regulatory mechanisms underlying tumorigenesis and progression.
                We are developing new methods to utilize the abundant public ChIP-seq data to infer functional enhancers that regulate the expression, and understand the targets and specificity of epigenetic drugs in cancers.

                We are developing the computational methods for the design (SSC), analysis (MAGeCK), hit prioritization (NEST), and visualization (VISPR) of genome-wide CRISPR screens.
                We are also using this technology to identify key genes in breast and prostate tumor progression and drug resistance.
                We also develop CRISPR screen platforms to understand the functions of enhancers and long-noncoding RNAs, and identify synthetic lethal gene pairs in cancer that leads to optimized cancer precision medicine.

            We are developing novel computational algorithms to systematically deconvolve the abundance of different immune cell types.
            Applying the deconvolution method on over 10K tumor samples from TCGA identified widespread clinical associations with tumor infiltrating immune cells.
            Our investigations on cancer vaccine and checkpoint blockade targets suggest that systematic analyses of tumor immunity have the potential to inform effective cancer immunotherapies.
