Personal Statement

My current research focuses on epigenetic and high throughput genomic data analysis in cancer study. Since January 2012, I have focused on Bioinformatics research such as developing whole genome DNA methylation data analysis pipeline using novel statistical model, RNA sequencing data analysis, microarray and sequencing based gene expression data analysis. In addition, I have developed a web-based statistical tool to predict recurrence of prostate cancer for patients after radiation therapy using Bayesian joint survival-longitudinal modeling. My research interests also include other traditional Biostatistics research including survival analysis, nonparametric analysis and ordered statistics analysis.
