Research Interests
My research interest centers around statistical applications in bioinformatics and computational biology. I am actively engaged in developing advanced statistical and machine learning methods and tools specifically designed for the analysis of large-scale, high-dimensional genomic and genetic data. Some of recent working topics include species number estimation, nucleosome positioning mapping and prediction, next-generation sequencing analysis, RNA-seq normalization, Ribo-seq pattern differentiation, CRISPR-cas9 cleavage efficiency prediction, prediction of DNA bendability and its relationship to chromosome functions and etc. My lab has developed a few software tools that have been frequently used by researchers, including SPECIES (for species number estimation, CRAN), NuPoP (for nucleosome positioning prediction, bioconductor), DegNorm (for degradation normalization for RNA-seq, bioconductor), RiboDiPA (for differential pattern analysis for Ribo-seq data, GitHub, bioconductor), DNAcycP (for DNA cyclizability/bendability prediction, GitHub, Web server) and BoostMEC (for CRISPR-cas9 cleavage efficiency prediction, GitHub).
