Probabilistic Short Read Alignments with Next Generation Sequencing (NGS) Data. To develop a probabilistic mapping algorithm to achieve a high-quality NGS alignments. The applications I primarily focus on include bisulfited reads for methylation profiling, RNA editing, and Single-nucleotide polymorphism(SNP) analysis.
Rapid Diagnosis of Pathogen with Clinical Samples. To design a statistical framework and develop a highly scalable algorithm to rapidly identify non-human sequences with the minimum read depth.
Genome-wide Methylation Data Analysis. To apply Kalman filter to bisulfited reads alignments and quantify a true methylation proifle across cells. Furthermore, a time-dependent autoregressive–moving-average model (ARMA) is applied to analyze a differentially methylated region (DMR).
